Refactor: Remove deprecated gRPC service files and implement new API structure

- Deleted old gRPC service definitions in `game_grpc.pb.go` and `public.go`.
- Added new API server implementations for objectstory, player, and shop services.
- Introduced configuration files for new APIs in `etc/*.yaml`.
- Created main entry points for each service in `objectstory.go`, `player.go`, and `shop.go`.
- Removed unused user update handler and user API files.
- Added utility functions for context management and HTTP header parsing.
- Introduced PostgreSQL backup configuration in `backup/postgreSql.yaml`.
