Add IPMI FRU editor to Tools page

- New card "IPMI — FRU" on Tools page (device 0, in-band)
- Read: GET /api/tools/ipmi-fru → ipmitool fru print 0 → editable table
- Editable fields: chassis (part#, serial, extra), board (mfr, product, serial, part#),
  product (mfr, name, part#, version, serial); read-only fields displayed as text
- Write: POST /api/tools/ipmi-fru/write → task → backup to fru-backups/ → ipmitool fru edit per field
- Dirty tracking + Save (N changed) button, same UX as Supermicro DMI card

+# Decision: Skip PCIe link-speed warnings for disabled devices
+
+**Date:** 2026-06-12
+**Status:** active
+
+## Context
+
+On HGX H100 SXM5 baseboards, the Microchip Switchtec PM41028 PSX PCIe switch
+(vendor 11F8, device 4128, NVIDIA subsystem 10DE:1643) appears in `lspci` as a
+"Memory controller". Its upstream link trains at Gen3 x2 while the device is
+capable of Gen4 x16. The device is permanently in a disabled state: memory access
+and bus-mastering are both off (Mem-, BusMaster-); `/sys/bus/pci/devices/<bdf>/enable`
+reads `0`.
+
+This chip is the PCIe fabric management endpoint for the NVSwitch interconnect — it
+carries only management traffic at low bandwidth and is intentionally not activated
+by any Linux driver. The bee audit was reporting a `statusWarning` with message
+"PCIe link speed degraded" for this device, which is misleading because the device
+is not in the data path.
+
+## Decision
+
+`applyPCIeLinkSpeedWarning` reads `/sys/bus/pci/devices/<bdf>/enable` via the
+existing `readPCIIntAttribute` helper. If the value is `0` the function returns
+early without setting any warning status.
+
+The check is vendor-agnostic: it applies to any PCIe device that Linux has not
+activated, regardless of make or model. This is consistent with the
+`no-hardcoded-vendors` contract — no vendor ID, device ID, or name string is
+used as a condition.
+
+## Consequences
+
+- PCIe fabric management endpoints, IPMI virtual devices, and other permanently
+  disabled PCIe functions no longer produce spurious link-degradation warnings.
+- Real link degradation on active devices (GPUs, NICs, NVMe, NVLink bridges)
+  continues to be detected and reported as before.
+- NVLink bridge cards retain their existing `statusCritical` path (they are always
+  enabled, so the early return is never taken for them).
+- The Switchtec device on HGX H100 boards shows `statusOK` with no
+  `error_description` in the audit JSON.

+# GRUB Bitmap Error History
+
+## Symptom
+
+On some servers GRUB prints:
+
+```text
+error: null src bitmap in grub_video_bitmap_create_scaled.
+Press any key to continue...
+```
+
+The important new observation as of `v10.7` is:
+
+- the error still appears even when the logo image block is removed from
+  `iso/builder/config/bootloaders/grub-efi/live-theme/theme.txt`
+- therefore the current error can no longer be explained only by
+  `bee-logo.png` / `bee-logo.tga`
+
+That does not prove the theme system is healthy. It proves only that the
+currently remaining failure is deeper than "bad logo file".
+
+## Current State
+
+Current source files:
+
+- [iso/builder/config/bootloaders/grub-efi/live-theme/theme.txt](/Users/mchusavitin/Documents/git/bee/iso/builder/config/bootloaders/grub-efi/live-theme/theme.txt:1)
+  has no `image` block anymore
+- [iso/builder/config/bootloaders/grub-efi/config.cfg](/Users/mchusavitin/Documents/git/bee/iso/builder/config/bootloaders/grub-efi/config.cfg:1)
+  still does `insmod tga` and then `source /boot/grub/theme.cfg`
+
+Implication:
+
+- if the error still fires, the trigger is likely elsewhere in GRUB theme
+  rendering or in the assets/config GRUB resolves while sourcing `theme.cfg`
+- the old "PNG parser fragility" story is no longer a sufficient explanation
+  for the current failure mode
+
+Current artifact facts:
+
+- the provided `easy-bee-nvidia-v10.7-amd64.logs` build logs reference
+  `linux-image-6.1.0-45`
+- the provided `easy-bee-nvidia-v10.7-amd64.iso` contains
+  `live/initrd.img-6.1.0-45-amd64` and `live/vmlinuz-6.1.0-45-amd64`
+- a later `BOOT FAILED!` screenshot showed `live/initrd.img-6.1.0-44-amd64`
+  and `live/vmlinuz-6.1.0-44-amd64`
+
+Implication:
+
+- the `BOOT FAILED!` screenshot is not from the same artifact as the provided
+  `v10.7` ISO/log set
+- until the exact ISO filename and checksum are tied to that failure, the
+  GRUB bitmap issue and the live-boot failure must be treated as separate
+  problems
+
+## Chronology
+
+### 1. Initial bee GRUB theme introduction
+
+Relevant commit:
+
+- `d52ec67` `Stability hardening, build script fixes, GRUB bee logo`
+
+What changed:
+
+- bee-branded GRUB theme introduced
+- image block with explicit `width` / `height`
+
+Observed result:
+
+- bitmap error appeared
+
+### 2. Remove explicit scaling dimensions
+
+Relevant commit:
+
+- `aa284ae` `fix(iso): avoid grub logo scaling error`
+
+What changed:
+
+- removed `width = 400`
+- removed `height = 400`
+
+Reason stated by the change:
+
+- try to avoid the scaling path
+
+Observed result:
+
+- error persisted
+
+Conclusion:
+
+- explicit width/height were not the sole trigger
+
+### 3. Rework PNG handling and menu rendering
+
+Relevant commit:
+
+- `6112094` `fix(grub): fix bitmap error and menu rendering`
+
+Commit message says the change was intended to:
+
+- convert `bee-logo.png` to RGBA and strip metadata
+- move `terminal_output gfxterm` before `insmod png` / theme load
+- remove ASCII banner from GRUB menu area
+- fix theme typography/layout fields
+
+Observed result:
+
+- error persisted
+
+Notes:
+
+- this was still operating under the assumption that the issue was the PNG
+  payload or the order of gfxterm/theme init
+
+### 4. Convert logo PNG back to RGB
+
+Relevant commit:
+
+- `333c44f` `Fix GRUB splash: convert bee-logo.png from RGBA to RGB`
+
+Intended reason:
+
+- GRUB might dislike RGBA PNG and want RGB PNG
+
+Observed result:
+
+- error still persisted according to later project notes
+
+### 5. Add post-build canonical GRUB/isolinux sync
+
+Relevant commit:
+
+- `0cdfbc5` `fix(iso): restore boot UX and boot logs`
+
+What this introduced:
+
+- post-`lb build` rewriting of `binary/boot/grub/grub.cfg`
+- post-`lb build` rewriting of `binary/isolinux/live.cfg`
+- forced rebuild of `binary_checksums`, `binary_iso`, `binary_zsync`
+
+Why it was added:
+
+- restore canonical EASY-BEE boot UX after live-build wrote its own bootloader
+  outputs
+- restore expected boot menu and logs
+
+Important note:
+
+- this commit did not directly solve the bitmap issue
+- it added a second layer of bootloader mutation after live-build
+
+### 6. Switch from PNG to TGA
+
+Relevant commit:
+
+- `626763e` `Fix GRUB bitmap error: switch from PNG to TGA for splash logo`
+
+Commit message says:
+
+- GRUB PNG reader was considered fragile
+- switch to uncompressed 24-bit TGA
+- `config.cfg`: `insmod png` -> `insmod tga`
+- `theme.txt`: `bee-logo.png` -> `bee-logo.tga`
+
+Observed result:
+
+- this did not eliminate the problem in the current lineage
+- today the system still errors even after the entire image block was removed
+
+Conclusion:
+
+- switching PNG -> TGA was not a durable root-cause fix
+
+### 7. Patch EFI image after build
+
+Relevant commit:
+
+- `4f20c92` `Make UEFI boot safe and remove GRUB logo`
+
+What this introduced:
+
+- `sync_efi_grub_theme_assets`
+- direct `mtools` patching of `efi.img`
+- copying `config.cfg`, `theme.cfg`, and `live-theme/*` into the EFI FAT image
+- removal of the logo image block from `theme.txt`
+
+Why it was added:
+
+- make UEFI path "safe"
+- keep EFI GRUB image aligned with canonical bootloader assets
+
+Observed result:
+
+- later this became the direct cause of `Disk full` during build once
+  `bee-logo.tga` was large enough
+- and even with the logo removed from `theme.txt`, the bitmap error still
+  remained
+
+Conclusion:
+
+- EFI post-build patching increased build complexity
+- removing the logo alone did not remove the runtime GRUB error
+
+### 8. Remove ASCII logo banners
+
+Relevant commit:
+
+- `14505ef` `Remove easy bee ASCII logo banners`
+
+What changed:
+
+- web loading page ASCII cleanup only
+
+Relevance here:
+
+- none for GRUB bitmap error
+- included here only to avoid confusion with other "logo removal" work
+
+### 9. Remove EFI post-build patching
+
+Relevant commit:
+
+- `5dc022d` `Drop post-build EFI bootloader patching`
+
+Why it was done:
+
+- stop mutating `efi.img` post-build
+- remove dependence on `mtools` for EFI patching
+- remove the `Disk full` failure mode
+
+Impact:
+
+- this did not target the GRUB bitmap error directly
+- it targeted build-system complexity and EFI image overflow
+
+### 10. Restore only GRUB/isolinux post-build sync
+
+Relevant commit:
+
+- `42774d4` `Restore post-build GRUB and isolinux sync`
+
+Why it was needed:
+
+- removing all post-build sync caused final ISO validation to fail with
+  missing canonical EASY-BEE boot entries
+- memtest was still fine, but final GRUB menu was no longer canonical
+
+What it restored:
+
+- only `binary/boot/grub/grub.cfg`
+- only `binary/isolinux/live.cfg`
+
+What it did not restore:
+
+- no EFI FAT image patching
+- no `mtools` path
+
+## What Is Proven False
+
+The current evidence rules out several simplistic explanations:
+
+- "the error is only caused by explicit image scaling"
+- "the error is only caused by PNG vs TGA"
+- "the error is only caused by the logo file itself"
+
+Why:
+
+- scaling dimensions were removed and error persisted
+- PNG was replaced with TGA and error still survived in the lineage
+- the image block itself is now absent, and the error still occurs
+
+## Working Hypotheses Left
+
+The remaining plausible layers are:
+
+- GRUB theme engine still tries to render some bitmap-related element even
+  without the logo image block
+- GRUB is resolving stale theme assets from the built EFI/ISO path rather than
+  what we think the source tree says
+- `theme.cfg` / `theme.txt` / GRUB module loading order still triggers a bitmap
+  code path elsewhere
+- live-build may still package a stale `theme.txt` or stale `live-theme`
+  directory into the final image
+- the GRUB environment on the failing hardware may behave differently from the
+  assumptions in our source tree
+
+## Decision Boundary
+
+Before making another change, the next step should be evidence gathering from
+the real built artifact, not another speculative edit.
+
+That means checking on the actual built ISO or EFI image:
+
+- exact `boot/grub/theme.cfg`
+- exact `boot/grub/live-theme/theme.txt`
+- exact contents of `boot/grub/live-theme/`
+- whether the final image still contains a stale logo reference
+- whether the EFI path and non-EFI path differ
