feature: Add TAK passphrase lock/unlock support

Browse source 
Implement the client-side TAK passphrase authentication flow for
  devices running TAK-locked firmware.

  Key components:
  - TakPassphraseStore: per-device passphrase persistence using
    EncryptedSharedPreferences (Android Keystore AES-256-GCM), with
    boot and hour TTL fields stored alongside the passphrase
  - TakLockHandler: orchestrates the full lock/unlock lifecycle —
    auto-unlock on reconnect using stored credentials, passphrase
    submission, token info parsing, and backoff/failure handling
  - MeshCommandSender: sendTakPassphrase() and sendTakLockNow() build
    plain local packets that bypass PKC signing and session_passkey;
    hour TTL is encoded as an absolute Unix epoch as required by firmware
  - ServiceRepository: TakLockState sealed class (None, Locked,
    NeedsProvision, Unlocked, LockNowAcknowledged, UnlockFailed,
    UnlockBackoff), TakTokenInfo (boots remaining + expiry epoch), and
    sessionAuthorized flag
  - TakUnlockDialog: Compose dialog for passphrase entry, shown on
    Locked and NeedsProvision states; onDismissRequest is a no-op to
    prevent race conditions with firmware response timing; cancel
    disconnects the user and navigates to the Connections tab
  - Lock Now (Security settings): immediately disconnects the client
    after informing firmware, purges cached config, navigates away
    without showing a passphrase dialog
  - ConnectionsScreen: suppress "region unset" prompt while the device
    is TAK-locked, since pre-auth config is zeroed/redacted and would
    lead the user to a blank LoRa settings screen
  - AIDL: sendTakUnlock() and sendTakLockNow() wired through
    MeshService → MeshActionHandler → TakLockHandler
  - Security settings: "Lock Now (TAK)" button and token info display
    showing boots remaining and expiry date
