Add attachments, pet selector, badges & search fix

Multiple UI and feature tweaks across app screens:

- chat_screen.dart: Add attachment bottom sheet and _AttachOption widget, implement animated send/mic button toggle, update message hint, wire text change state handling and show snackbars for unimplemented features.
- pet_care_screen.dart: Add per-pet selector in AppBar for users with multiple pets, integrate active pet provider, remove old _PetSelector, and adjust layout/TabBar sizing.
- pet_profile_screen.dart: Restyle action buttons (use FilledButton for Message, circular share InkWell) and adjust spacing.
- search_repository.dart: Fix search filter to query animal_type instead of species.
- search_screen.dart: Hook SearchBar.onChanged to _onSearch and update clear button to refresh UI state.
- settings_screen.dart: Add Achievements & Badges section (new UI, badge dialog and sharing via share_plus), import controllers/models needed.
- APP_SCREENS_AUDIT.md: Add new audit file.

These changes improve messaging attachments UX, multi-pet navigation, badges visibility and search correctness.
