Add biometric lock and rate limit handling

Biometric lock: opt-in Face ID/Touch ID/fingerprint app lock with toggle in ProfileScreen. Locks on background, requires auth on foreground return. Platform implementations: BiometricPrompt (Android), LAContext (iOS). Rate limit: 429 responses parsed with Retry-After header, user-friendly error messages in all 10 locales, retry plugin respects 429. ErrorMessageParser updated for both iOS Swift and KMM.
