Update CI to generate protobuf and Ent ORM files

- Add protoc installation step in all CI jobs (test, lint, build)
- Install protoc-gen-go and protoc-gen-go-grpc plugins
- Generate protobuf files using 'make generate-proto' before building/testing
- Generate Ent ORM files from ent/ directory before building/testing
- Ensures CI works correctly after removing generated files from git tracking
