Passkey-Anmeldung (WebAuthn) zusätzlich zum Passwort
- Tabelle passkeys + lib/passkeys.ts (CRUD, Counter-Replay-Schutz)
- lib/webauthn.ts: RP-Config via RP_ID/RP_ORIGIN/RP_NAME, Challenge im
httpOnly-Cookie, Wrapper um @simplewebauthn/server
- API: app/api/passkey/{register,authenticate,route}; authenticate ist
öffentlich (proxy.ts ausgenommen) und setzt bei Erfolg die Session
- Login-Button "Mit Passkey anmelden", Verwaltung im Einstellungen-Tab
- Passwort bleibt als Fallback; Version 0.1.1
