feat: update ApkList to use tabbed view

Replaced card-based layout with tabbed interface for APK environments.
Now displays APKs grouped by dev/product/sandbox/other tabs with counts.

- Replaced ApkCard with ApkTable component
- Added tab navigation with active state styling
- Group APKs by environment using reduce
- Show count badges for each environment tab
