fix(android): add missing badgeBackgroundColor and badgeTextColor to TabInfo

The TabInfo data class was missing badgeBackgroundColor and badgeTextColor
properties that RCTTabView.kt expects when applying badge colors.

This caused Android builds to fail with:
- Unresolved reference 'badgeBackgroundColor'
- Unresolved reference 'badgeTextColor'
- Unresolved reference 'colorError'

Changes:
- Add badgeBackgroundColor and badgeTextColor properties to TabInfo data class
- Populate them from JS bridge in setItems()
- Simplify badge color application to let Material use default theme colors
  when custom colors are not provided (avoids colorError resolution issues)

Fixes #481
