refactor: enhance OpenAPISyncTab functionality and clean up unused code (#7392)

- Updated OpenAPISyncTab to utilize Redux state for active tab management, improving state consistency.
- Removed unnecessary loading state checks from OverviewSection and SpecStatusSection for cleaner logic.
- Streamlined prop usage in OverviewSection by eliminating the isLoading prop.
- Cleaned up useOpenAPISync hook by removing unused state clearing logic on unmount.
- Improved file handling in openapi-sync IPC by ensuring new files are created in the appropriate folder based on tags.
