Fix React component loading state and unique ID issues

- Fix loading state: Initialize loading=true when searchSpaceId changes, await all fetch calls with Promise.all, and clear loading in finally block
- Fix unique ID lint issue: Replace static 'is_active' ID with React useId() generated stable ID
- Import useId hook and generate isActiveSwitchId for Switch component and Label
- Ensure loading spinner properly clears whether requests succeed or fail
- Make component more accessible with proper unique IDs
