James Rich 092238cb55 refactor: use injected ioDispatcher and ApplicationCoroutineScope 
Replaces two coroutine anti-patterns flagged by the architecture audit:

* FirmwareUpdateViewModel.onCleared() was using GlobalScope.launch to
  run cleanup work that must outlive the ViewModel scope. Introduce a
  new ApplicationCoroutineScope marker interface + Koin @Single binding
  in core/common, backed by SupervisorJob() + ioDispatcher, and inject
  it into the VM. NonCancellable is preserved so shutdown work still
  cannot be interrupted. Verified end-to-end by the KoinVerificationTest
  full-graph check.
* Six sites in feature/settings (android+jvm LogExporter/PrefExporter)
  and core/ui (android+jvm PlatformUtils) were hardcoding Dispatchers.IO.
  Switch to the project's injectable ioDispatcher property so tests
  can substitute a test dispatcher without reflection.

Dispatchers.Main sites in LogExporter are intentionally left alone —
they are fully test-swappable via Dispatchers.setMain() and there is
no existing mainDispatcher property to inject.

: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.
