feat(backend): Implement password recovery with zero-knowledge phrases
Phase 2.4 - Password Recovery Feature Features implemented: - Zero-knowledge password recovery using recovery phrases - Recovery phrases hashed with PBKDF2 (same as passwords) - Setup recovery phrase endpoint (protected) - Verify recovery phrase endpoint (public) - Reset password with recovery phrase endpoint (public) - Token invalidation on password reset - Email verification stub fields added to User model New API endpoints: - POST /api/auth/recovery/setup (protected) - POST /api/auth/recovery/verify (public) - POST /api/auth/recovery/reset-password (public) User model updates: - recovery_phrase_hash field - recovery_enabled field - email_verified field (stub) - verification_token field (stub) - verification_expires field (stub) Security features: - Zero-knowledge proof (server never sees plaintext) - Current password required to set/update phrase - All tokens invalidated on password reset - Token version incremented on password change Files modified: - backend/src/models/user.rs - backend/src/handlers/auth.rs - backend/src/main.rs - backend/src/auth/jwt.rs Documentation: - backend/PASSWORD-RECOVERY-IMPLEMENTED.md - backend/test-password-recovery.sh - backend/PHASE-2.4-TODO.md (updated progress)
