feat(server): introduce admin reset functionality and enhance user management

- Added a new `reset-admin` script to reset or create the admin username and password.
- Updated the README to include instructions for resetting the admin login.
- Enhanced user management by allowing username updates during admin reset.
- Defaulted new resources to the internal namespace `local` for better organization.
- Removed unused owner selection from various components to streamline the UI.
