1. Verbose live progress during SAT tests (CPU, Memory, Storage, AMD GPU)

- New tui/sat_progress.go: polls {DefaultSATBaseDir}/{prefix}-*/verbose.log every 300ms and parses completed/in-progress steps
  - Busy screen now shows each step as PASS  lscpu (234ms) / FAIL  stress-ng (60.0s) / ...   sensors-after instead of just "Working..."

  2. Test results shown on screen (instead of just "Archive written to /path")
  - RunCPUAcceptancePackResult, RunMemoryAcceptancePackResult, RunStorageAcceptancePackResult, RunAMDAcceptancePackResult now read summary.txt from the run directory and return a formatted per-step result:
  Run: 2025-03-25T10:00:00Z

  PASS  lscpu
  PASS  sensors-before
  FAIL  stress-ng
  PASS  sensors-after

  Overall: FAILED  (ok=3  failed=1)

  3. AMD GPU SAT with auto-detection
  - platform.System.DetectGPUVendor(): checks /dev/nvidia0 → "nvidia", /dev/kfd → "amd"
  - platform.System.RunAMDAcceptancePack(): runs rocm-smi, rocm-smi --showallinfo, dmidecode
  - GPU SAT (G key / GPU row enter) automatically routes to AMD or NVIDIA based on detected vendor
  - "Run All" also auto-detects vendor

  4. Panel detail view
  - GPU detail now shows the most recent (NVIDIA or AMD) SAT result, whichever is newer
  - All SAT detail views use the same human-readable formatSATDetail format
