🐛 fix: sub-step default expanded, real-time checkbox, startup freeze, color sync

1. SubStepFrame defaults to expanded (▼), not collapsed
2. erase_all checkbox has command=_on_erase_toggle → immediate config update
3. _deferred_init runs _check_vitis/_refresh_ports in background thread
   Fixes UI freeze during startup (subprocess.run for tool versions)
4. Sub-step colors now match StepHeader:
   - pending: gray ACCENT_PENDING (#888888)
   - running: blue CIRCLE_RUNNING (#0078D4) with pulse animation
   - complete: green ACCENT_COMPLETE (#107C10)
   - error: red ACCENT_ERROR (#D13438)
   - Running sub-step pulses between light/dark blue like StepHeader
