feat(backend): Simplify caching to just store routes (#11140)

### Problem
Limits caching to just the main marketplace routes

### Changes 🏗️

- **Simplified store cache implementation** in
`backend/server/v2/store/cache.py`
  - Streamlined caching logic for better maintainability
  - Reduced complexity while maintaining performance
  
- **Added cache invalidation on store updates**
  - Implemented cache clearing when new agents are added to the store
- Added invalidation logic in admin store routes
(`admin_store_routes.py`)
  - Ensures all pods reflect the latest store state after modifications

- **Updated store database operations** in
`backend/server/v2/store/db.py`
  - Modified to work with the new cache structure
  
- **Added cache deletion tests** (`test_cache_delete.py`)
  - Validates cache invalidation works correctly
  - Ensures cache consistency across operations

### Checklist 📋

#### For code changes:
- [x] I have clearly listed my changes in the PR description
- [x] I have made a test plan
- [x] I have tested my changes according to the test plan:
  - [x] Verify store listings are cached correctly
  - [x] Upload a new agent to the store and confirm cache is invalidated
