feat: implement autocomplete component and enhance server mock functionality

- Introduced a new Autocomplete component for improved user experience in selecting options across various UI components.
- Refactored BranchAutocomplete and CategoryAutocomplete to utilize the new Autocomplete component, streamlining code and enhancing maintainability.
- Updated Playwright configuration to support mock agent functionality during CI/CD, allowing for simulated API interactions without real calls.
- Added comprehensive end-to-end tests for feature lifecycle, ensuring robust validation of the complete feature management process.
- Enhanced auto-mode service to support mock responses, improving testing efficiency and reliability.
