Phase 2: Update dependencies with breaking changes

- Firebase BOM: 33.3.0 → 34.1.0
  * BREAKING: Removed all KTX modules - must use main modules
  * BREAKING: Removed deprecated Dynamic Links
  * Minimum SDK already compatible (23)

- Play Services Ads: 23.3.0 → 24.5.0
  * BREAKING: SDK v24 has significant API changes
  * Includes UMP SDK 3.2.0, placement ID support, ad inspector
  * Performance improvements and crash fixes

NOTE: These updates require testing. Firebase KTX module migration
may require code changes if KTX modules were used. Play Services Ads
v24 migration guide should be reviewed.
