- Remove duplicate CoreModule() calls from all service main.go files
- NewContainer() already includes CoreModule() automatically
- This was causing duplicate ConfigProvider provider errors
- Update all _fx.go files to use *database.Client instead of *ent.Client
- database.Client embeds *ent.Client, so it can be used directly
- This fixes type mismatches between providers and consumers
- Keep ent import for constants like ent.Desc
- All services now build and should start successfully
