Senko-san 7a17e3babd feat(subsonic): per-user encrypted app-password foundation
Subsonic auth (t=md5(password+salt), legacy p=) needs a recoverable secret,
but login passwords are stored as a one-way argon2 hash. Add a separate,
per-user app-password: high-entropy, random, and encrypted at rest with a
Fernet key derived from SUBSONIC_SECRET_KEY (never stored in the DB).

- SubsonicPasswordCipher + generate_subsonic_password in core.security
- users.subsonic_password_enc column (+ Alembic migration), repo + port methods
- SubsonicAuthService: verify (t+s / p / p=enc:) and rotate/reveal lifecycle
- self-service GET/POST /users/me/subsonic-password + admin rotate endpoint
- domain SubsonicCredentials + SubsonicCipher port; deps wiring
