niccellular 6ce565f16c feat(lockdown): thread max_session_seconds through coordinator and UI
End-to-end plumbing for LockdownAuth.max_session_seconds (per-boot
uptime cap on the unlocked session; 0 = unlimited).

Wire:
- CommandSenderImpl populates LockdownAuth.max_session_seconds in the
  outbound admin packet (clamped non-negative).

Coordinator + persistence:
- LockdownCoordinator.submitPassphrase gains optional maxSessionSeconds
  (default 0); persisted alongside boots/hours and replayed by
  auto-unlock so cached sessions keep the operator's cap on reconnect.
- StoredPassphrase gains a new field with a default of 0 so existing
  call sites stay source-compatible.
- LockdownPassphraseStore (Android EncryptedSharedPreferences impl):
  reads/writes the new field with a `_maxSessionSeconds` key suffix;
  legacy entries decode to 0.
- LockdownPassphraseStore (JVM file-backed impl): bumps the per-entry
  on-disk serialization from 3-line to 4-line; legacy 3-line entries
  still decode (treated as maxSessionSeconds=0).

IPC + radio plumbing:
- IMeshService.sendLockdownUnlock AIDL gains a 4th int parameter.
- MeshService stub, MeshActionHandler, RadioController interface, and
  both impls (AndroidRadioControllerImpl, DirectRadioControllerImpl)
  thread the field through.
- FakeIMeshService, FakeRadioController, FakeLockdownCoordinator
  updated to match.

UI:
- LockdownDialog adds a single optional "Session cap (minutes)" field
  below the boots/hours row. Operators enter minutes for ergonomics;
  the dialog multiplies by 60 before passing to the coordinator. Blank
  or 0 = unlimited (firmware default).
- UIViewModel.sendLockdownUnlock gains the new param with default 0.
- New string resources: lockdown_session_minutes,
  lockdown_session_minutes_help. Strings re-sorted via
  scripts/sort-strings.py.
