Add real-data duration estimates to benchmark and burn pages

- Add BenchmarkEstimated* constants to benchmark_types.go from _v8 logs
  (Standard Perf ~16 min, Standard Power Fit ~43 min, Stability Perf ~92 min)
- Update benchmark profile dropdown to show Perf / Power Fit timing per profile
- Add timing columns to Method Split table (Standard vs Stability per run type)
- Update burn preset labels to show "N min/GPU (sequential) or N min (parallel)"
- Clarify burn "one by one" description with sequential vs parallel scaling

+## Bootloader sync rule
+
+The ISO has two independent bootloader configs that must be kept in sync manually:
+
+| File | Used by |
+|------|---------|
+| `config/bootloaders/grub-efi/grub.cfg` | UEFI (all modern servers) |
+| `config/bootloaders/isolinux/live.cfg.in` | CSM / legacy BIOS (syslinux) |
+
+live-build does NOT derive one from the other. Any new boot entry, kernel parameter
+change, or new mode added to one file must be manually mirrored in the other.
+
+**Canonical entry list** (both files must have all of these):
+
+| Label | Key params |
+|-------|-----------|
+| normal (default) | `nomodeset bee.nvidia.mode=normal` + full param set |
+| load to RAM | `toram nomodeset bee.nvidia.mode=normal` + full param set |
+| GSP=off | `nomodeset bee.nvidia.mode=gsp-off` + full param set |
+| KMS | no `nomodeset`, `bee.nvidia.mode=normal` + full param set |
+| KMS + GSP=off | no `nomodeset`, `bee.nvidia.mode=gsp-off` + full param set |
+| fail-safe | `nomodeset bee.nvidia.mode=gsp-off noapic noapm nodma nomce nolapic nosmp` |
+
+**Full standard param set** (append after `@APPEND_LIVE@` / `nomodeset` flags):
+```

+numa_balancing=disable pcie_aspm=off intel_idle.max_cstate=1 processor.max_cstate=1
+nowatchdog nosoftlockup
+```
+(fail-safe is the exception — it deliberately uses minimal params.)
+
+**Historical note:** `grub-pc/` was mistakenly used instead of `grub-efi/` until v8.25.
+live-build reads `config/bootloaders/grub-efi/` for UEFI because the build is
+configured with `--bootloaders "grub-efi,syslinux"`. Directory `grub-pc` is ignored.
+
 ## Memtest rule
 
 Do not assume live-build's built-in memtest integration is sufficient for `bee`.
