Improved Error Messages

[Roaster05]

Description

This draft PR enhances error messages for end users by replacing memory references with custom messages based on error codes and locations. These changes improve the clarity and usability of the error messages.

Key Updates

• Implemented custom error messages for the project_handler module.
• Errors now provide detailed and actionable information.
  Examples:
  • ERRO[0000] failed to create project: Project abc already exists
  • ERRO[0001] failed to delete project: Project my_project not found or already deleted
• Error codes and types are mapped from the endpoint documentation:
  Harbor Go Client Documentation.

Notes

• Current changes are restricted to the project_handler module.
• Additional modules will be updated after approval of this approach.

@bupd the prefix is generated by the Errorf method of the fmt module, it we want to remove it we can use the Print method only, should i make that change?
