chore: update .gitignore and remove quick insert options from button configurations

- Added new entries to .gitignore for multi-agent MCP task queue and related rules.
- Removed "즉시 저장" (quick insert) options from the ScreenSettingModal and BasicTab components to streamline button configurations.
- Cleaned up unused event options in the V2ButtonConfigPanel to enhance clarity and maintainability.

These changes aim to improve project organization and simplify the user interface by eliminating redundant options.
