fix: invalidate home cache when updating read progress

Browse Source 
- Add cache tags support to BaseApiService
- Tag home data with 'home-data' tag in HomeService
- Use revalidateTag('home-data', 'max') after read progress updates
- With 'max' profile: serve stale while fetching fresh in background
