Fix IPMI hangs, add VROC license, fix blackbox service, drop qrencode

IPMI hang fix (Lenovo XCC SR650 V3):
- Add pluggable ipmi_profile system with per-vendor timeouts and fruEarlyExit flag
- Lenovo profile: 90s FRU timeout, streaming early-exit stops after PSU blocks found
- collectFRUEarlyExit streams ipmitool fru print and kills process once PSU blocks
  are followed by a non-PSU header (~6s instead of ~108s on 54-device FRU list)
- collectBMCFirmware and collectPSUs accept manufacturer and apply profile timeouts

VROC license detection:
- Detect VMD/VROC controller in PCIe list, run mdadm --detail-platform
- Parse "License:" line; store as snap.VROCLicense in HardwareSnapshot

Blackbox service fix:
- bee-blackbox.service was missing from systemctl enable list in ISO build hook
- Service never started on boot; state file never written; UI button stayed "Enable"

Drop qrencode:
- Remove from package list, standardTools API check, and runtime-flows doc
