fix: battery optimization prompt — add missing manifest permission and fix fallback

REQUEST_IGNORE_BATTERY_OPTIMIZATIONS intent is silently dropped without
the matching manifest permission. Added it to app.json permissions.
Also replaced .catch() chain (which only triggers on thrown errors) with
try/catch blocks so the fallback to IGNORE_BATTERY_OPTIMIZATION_SETTINGS
actually fires. Added resetBatteryOptPrompt() helper to re-trigger the
prompt during testing.
