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.

:feature:settings

Overview

The :feature:settings module manages all application and radio-side configurations. This includes user preferences, channel configuration, and advanced radio settings.

Key Components

1. SettingsScreen

The main entry point for application-wide settings.

2. RadioConfigViewModel

Handles the complex logic of reading and writing configuration to the Meshtastic device over the radio link (BLE, USB, or TCP).

3. AboutScreen

Displays version information, licenses, and project links.

Features

  • Channel Configuration: Manage encryption keys, channel names, and radio frequency settings.
  • Node Database Management: Options to clear or prune the local and remote node databases.
  • App Preferences: Theme selection, unit system (metric/imperial), and notification settings.
