- Admin enabled by default (was opt-in via env var)
- New /admin/status (public) and /admin/setup (first-run only) endpoints
- Setup endpoint locked after first use (returns 403)
- Admin password persisted to SQLite config table (survives restarts)
- Change password now persists to DB (was in-memory only)
- Frontend router guard forces /admin redirect until setup is complete
- AdminSetup.vue wizard: username + password + confirm
- Public config exposes admin_enabled/admin_setup_complete for frontend
- TLS warning only fires when password is actually configured
