fix(iso): restore memtest menu entries and validate ISO

Web UI / logs:
- Strip ANSI escape codes and handle \r (progress bars) in task log output
- Add USB export API + UI card on Export page (list removable devices, write audit JSON or support bundle)
- Add Display Resolution card in Tools (xrandr-based, per-output mode selector)
- Dashboard: audit status banner with auto-reload when audit task completes

Boot & install:
- bee-web starts immediately with no dependencies (was blocked by audit + network)
- bee-audit.service redesigned: waits for bee-web healthz, sleeps 60s, enqueues audit via /api/audit/run (task system)
- bee-install: fix GRUB UEFI — grub-install exit code was silently ignored (|| true); add --no-nvram fallback; always copy EFI/BOOT/BOOTX64.EFI fallback path
- Add grub-efi-amd64, grub-pc, grub-efi-amd64-signed, shim-signed to package list (grub-install requires these, not just -bin variants)
- memtest hook: fix binary/boot/ not created before cp; handle both Debian (no extension) and upstream (x64.efi) naming
- bee-openbox-session: increase healthz wait from 30s to 120s

KVM console stability:
- runCmdJob: syscall.Setpriority(PRIO_PROCESS, pid, 10) on all stress subprocesses
- lightdm.service.d: Nice=-5 so X server preempts stress processes

Packages: add btop

+# Charting architecture
+
+## Decision: one chart engine for all live metrics
+
+**Engine:** `github.com/go-analyze/charts` (pure Go, no CGO, SVG output)
+**Theme:** `grafana` (dark background, coloured lines)
+
+All live metrics charts in the web UI are server-side SVG images served by Go
+and polled by the browser every 2 seconds via `<img src="...?t=now">`.
+There is no client-side canvas or JS chart library.
+
+### Why go-analyze/charts
+
+- Pure Go, no CGO — builds cleanly inside the live-build container
+- SVG output — crisp at any display resolution, full-width without pixelation
+- Grafana theme matches the dark web UI colour scheme
+- Active fork of the archived wcharczuk/go-chart
+
+### SAT stress-test charts
+
+The `drawGPUChartSVG` function in `platform/gpu_metrics.go` is a separate
+self-contained SVG renderer used **only** for completed SAT run reports
+(HTML export, burn-in summaries). It is not used for live metrics.
+
+### Live metrics chart endpoints
+
+| Path | Content |
+|------|---------|
+| `GET /api/metrics/chart/server.svg` | CPU temp, CPU load %, mem load %, power W, fan RPMs |
+| `GET /api/metrics/chart/gpu/{idx}.svg` | GPU temp °C, load %, mem %, power W |
+
+Charts are 1400 × 280 px SVG. The page renders them at `width: 100%` in a
+single-column layout so they always fill the viewport width.
+
+### Ring buffers
+
+Each metric is stored in a 120-sample ring buffer (2 minutes of history at 1 Hz).
+Buffers are per-server or per-GPU and grow dynamically as new GPUs appear.

+# ISO Build Rules
+
+## Verify package names before use
+
+ISO builds take 30–60 minutes. A wrong package name wastes an entire build cycle.
+
+**Rule: before adding any Debian package name to the ISO config, verify it exists and check its file list.**
+
+Use one of:
+- `https://packages.debian.org/bookworm/<package-name>` — existence + description
+- `https://packages.debian.org/bookworm/amd64/<package-name>/filelist` — exact files installed
+- `apt-cache show <package>` inside a Debian bookworm container
+
+This applies to:
+- `iso/builder/config/package-lists/*.list.chroot`
+- Any package referenced in bootloader configs, hooks, or overlay scripts
+
+## Memtest rule
+
+Prefer live-build's built-in memtest integration over custom hooks or hardcoded
+bootloader paths. If you ever need to reference memtest files manually, verify
+the exact package file list first for the target Debian release.

+# Validate vs Burn: Hardware Impact Policy
+
+## Validate Tests (non-destructive)
+
+Tests on the **Validate** page are purely diagnostic. They:
+
+- **Do not write to disks** — no data is written to storage devices; SMART counters (power-on hours, load cycle count, reallocated sectors) are not incremented.
+- **Do not run sustained high load** — commands complete quickly (seconds to minutes) and do not push hardware to thermal or electrical limits.
+- **Do not increment hardware wear counters** — GPU memory ECC counters, NVMe wear leveling counters, and similar endurance metrics are unaffected.
+- **Are safe to run repeatedly** — on new, production-bound, or already-deployed hardware without concern for reducing lifespan.
+
+### What Validate tests actually do
+
+| Test | What it runs |
+|---|---|
+| NVIDIA GPU | `nvidia-smi`, `dcgmi diag` (levels 1–4 read-only diagnostics) |
+| Memory | `memtester` on a limited allocation; reads/writes to RAM only |
+| Storage | `smartctl -a`, `nvme smart-log` — reads SMART data only |
+| CPU | `stress-ng` for a bounded duration; CPU-only, no I/O |
+| AMD GPU | `rocm-smi --showallinfo`, `dmidecode` — read-only queries |
+
+## Burn Tests (hardware wear)
+
+Tests on the **Burn** page run hardware at maximum or near-maximum load for extended durations. They:
+
+- **Wear storage**: write-intensive patterns can reduce SSD endurance (P/E cycles).
+- **Stress GPU memory**: extended ECC stress tests may surface latent defects but also exercise memory cells.
+- **Accelerate thermal cycling**: repeated heat/cool cycles degrade solder joints and capacitors over time.
+- **May increment wear counters**: GPU power-on hours, NVMe media wear indicator, and similar metrics will advance.
+
+### Rule
+
+> Run **Validate** freely on any server, at any time, before or after deployment.
+> Run **Burn** only when explicitly required (e.g., initial acceptance after repair, or per customer SLA).
+> Document when and why Burn tests were run.
