Add security improvements: refresh tokens, passkeys, CSP, audit logging, TOTP encryption

- Shorten access token to 30min with 7-day refresh token flow
- Add WebAuthn passkey registration and login with TOTP fallback
- Add Content-Security-Policy header
- Add audit logging middleware to /volume1/docker/nas-dashboard/audit.log
- Block /volume1/docker/ in files endpoint
- Encrypt TOTP secret at rest with Fernet (derived from SECRET_KEY)
- New deps: py_webauthn, cryptography
