🧪 Regression Guard: Fix background service stop exceptions

[yuga-hashimoto]

Fix background service stop exceptions

This change addresses a stability issue where calling context.stopService(intent) inside exception handlers in Android services could crash the app if the stop service call itself fails. By wrapping the stopService calls in a try-catch block, we prevent cascading crashes when recovering from failed background service execution limits or security limits.

Changes made:

• Wrapped context.stopService(intent) calls with try-catch inside error handling blocks in:
  • HotwordService.kt
  • NodeForegroundService.kt
  • SessionForegroundService.kt

Testing:

• Ran app:lintStandardDebug successfully.
• Executed app:testStandardDebugUnitTest successfully with dummy google-services.json file.
