Refactor: Remove unused files and implement versioning support

- Deleted go.sum.license and storage.go files as they are no longer needed.
- Enhanced code generation to support versioned projects by introducing a new `IsVersioned` flag.
- Updated handler templates to differentiate between versioned and legacy modes for resource creation, updates, and deletions.
- Added resource prefix registration to ensure proper UID generation for versioned resources.
- Improved event publishing logic to accommodate versioned resources.
