Develop - WearOS - Device controls and info sync support

[sameerasw]

This pull request introduces major enhancements for integrating smartwatch (Wear OS) features, particularly enabling remote device locking and flashlight control from a connected watch. It adds new services, UI components, and settings to facilitate device info sync, remote lock configuration, and flashlight actions via wearable communication.

Key changes include:

Wear OS Integration & Device Sync:

• Added DeviceInfoSyncManager to handle periodic and on-demand syncing of device information (battery, ringer mode, flashlight state, etc.) with connected Wear OS devices, including flashlight intensity support and debounced updates. (DeviceInfoSyncManager.kt)
• Registered EssentialsWearableListenerService in the manifest to listen for messages from Wear OS (e.g., requests to sync device info, toggle flashlight, change sound mode, or lock the device). (AndroidManifest.xml, EssentialsWearableListenerService.kt) [1] [2]

Remote Lock from Watch Feature:

• Introduced the "Lock from Watch" feature in the registry, allowing users to configure remote locking behavior (screen off or device admin lock) from the watch. (FeatureRegistry.kt, SettingsRepository.kt, RemoteLockSettingsUI.kt) [1] [2] [3]
• Integrated the remote lock settings UI into the feature settings activity, with permission prompts for accessibility and device admin modes. (FeatureSettingsActivity.kt)

Flashlight Control Improvements:

• Expanded the flashlight broadcast receiver to support new actions for toggling and setting intensity, and ensured these actions can be triggered via the accessibility service for remote control. (AndroidManifest.xml, ScreenOffAccessibilityService.kt) [1] [2] [3]

UI & ViewModel Enhancements:

• Updated the watch settings UI and view model to support the new features and ensure correct initialization when accessing watch-related settings. (FeatureSettingsActivity.kt, WatchSettingsUI.kt) [1] [2]

These changes collectively provide robust support for smartwatch-driven device management, including secure remote locking and advanced flashlight control.
