feat: Implement automatic equipment code generation and allocation in equipment registration

- Enhanced the equipment registration process to support automatic code generation based on predefined numbering rules.
- Integrated API calls to fetch and preview numbering rules, allowing for dynamic equipment code assignment.
- Added error handling to manage failures in code allocation, ensuring a smoother user experience during equipment registration.
- Updated the input field for equipment code to reflect automatic generation status, improving clarity for users.
- These changes aim to streamline the equipment management process and enhance usability across multiple company implementations.
