feat: zero-knowledge recovery (Phase 2) — wrapped-DEK model
Introduces a wrapped-DEK recovery model so a forgotten password doesn't lose all encrypted data. The encryption key becomes a random DEK (not derived from the password); the DEK is wrapped under both a password-derived KEK and a recovery-phrase-derived KEK, and both wrapped forms are stored on the server. Crypto (crypto/keys.ts): - DEK generation (random AES-256-GCM), KEK derivation (PBKDF2 password/recovery), wrapDek/unwrapDek/rewrapDek. - setupEncryption(password, recoveryPhrase?) — generates a DEK, wraps under both KEKs, returns wrapped forms + recovery proof. - unlockWithPassword(password, wrappedDek) — derives password KEK, unwraps DEK. - unlockWithRecovery(phrase, wrappedDek) — derives recovery KEK, unwraps DEK. Backend: - User model: wrapped_dek, wrapped_dek_iv, recovery_wrapped_dek, recovery_wrapped_dek_iv fields. - RegisterRequest accepts wrapped-DEK fields; stored verbatim. - AuthResponse returns wrapped_dek + wrapped_dek_iv (for login unwrapping). - New GET /api/auth/recovery-info?email= — returns recovery-wrapped DEK. - RecoverPasswordRequest gains new_wrapped_dek + new_wrapped_dek_iv. - change-password also accepts + stores re-wrapped DEK. Frontend: - Auth store: login unwraps DEK from response; new recover() action fetches recovery-wrapped DEK, unwraps with phrase, re-wraps under new password. - RecoveryPage (new): email + recovery phrase + new password flow. - LoginPage: 'Forgot password? Recover' link. App.tsx: /recover route. Verified: backend 21 tests, 0 warnings; frontend build clean, 20 tests.

* - DEK (Data Encryption Key): a random AES-256-GCM key used to encrypt/decrypt
|

* all user data. Lives in memory only.
|

* - KEK (Key Encryption Key): derived from the password (or recovery phrase)
|
||||
* via PBKDF2. Used to wrap (encrypt) the DEK for storage on the server.
|
||||
*
|
||||
* - `authSecret`: base64 bytes sent to the server as the "password". The
|
||||
* server PBKDF2-hashes it (as it always has). The server can never derive
|
||||
* the encryption key from this value.
|
||||
* - `encKey`: an AES-GCM CryptoKey kept in memory only (never persisted,
|
||||
* never transmitted). Used to encrypt/decrypt all user data.
|
||||
* The server stores two wrapped forms of the DEK:
|
||||
* - password_wrapped_dek: DEK encrypted under KEK(password)
|
||||
* - recovery_wrapped_dek: DEK encrypted under KEK(recovery_phrase)
|

* Two separate PBKDF2 passes with app-wide domain-separation salts prevent the

* server from deriving `encKey` even if it logs or leaks `authSecret`.
