Data Manager & App Usage

8/2/2026

Renamed tabs to "Data Usage", "Time Usage", and "App Usage" for clarity
•
Added interactive bar/line charts with toggle to Data Usage and Time Usage tabs
•
Added pie chart (top 4 apps + Other) to App Usage tab
•
Added search bar and column toggle (1-4 columns) to App Usage tab
•
Added "Show More / Show Less" for app list — only 3 rows shown initially for faster rendering
•
App Usage now reads directly from Room DB instead of Android API, eliminating UI freezes
