Fetch category_alert_preferences specifically for phones

The key is overloaded between watches & phones. On
phones it is a PreferenceCategory and on watches it
is a PreferenceScreen.

Avoid cast crash by only fetching it as a PreferenceCategory
if running on a phone.

Bug: 72623900
Test: manual, does not crash anymore
