fix: Vault seeding, service health checks, and restart idempotency

- Replace hardcoded passwords with generate_random_string() for all Vault-seeded services
- Add valkey-cli, nc to SafeCommand allowlist; fix PATH in all 4 execution methods
- Fix empty Vault KV values ('none' placeholder) preventing 'Failed to parse K=V' errors
- Fix special chars in generated passwords triggering shell injection false positives
- Add ALM app.ini creation with absolute paths for Forgejo CLI
- Increase Qdrant timeout 15s→45s, ALM wait 5s→20s
- Persist file_states and kb_states to disk for .bas/KB idempotency across restarts
- Add duplicate check to use_website registration (debug log for existing)
- Remove dead code (SERVER_START_EPOCH, server_epoch)
- Add generate_random_string() to shared mod.rs, remove duplicates
