feat(core): use cloud indexer for search (#12899)

<!-- This is an auto-generated comment: release notes by coderabbit.ai

## Summary by CodeRabbit

- **New Features**
- Added enhanced error handling and user-friendly error messages in
quick search and document search menus.
  - Introduced loading state indicators for search operations.
  - Quick Search now provides explicit error feedback in the UI.

- **Improvements**
- Search and aggregation operations can now prefer remote or local
indexers based on user or system preference.
- Streamlined indexer logic for more consistent and reliable search
experiences.
- Refined error handling in messaging and synchronization layers for
improved stability.
- Enhanced error object handling in messaging for clearer error
propagation.
- Updated cloud workspace storage to always use IndexedDB locally and
CloudIndexer remotely.
- Shifted indexer operations to use synchronized indexer layer for
better consistency.
  - Simplified indexer client by consolidating storage and sync layers.
- Improved error propagation in messaging handlers by wrapping error
objects.
- Updated document search to prioritize remote indexer results by
default.

- **Bug Fixes**
- Improved robustness of search features by handling errors gracefully
and preventing potential runtime issues.

- **Style**
  - Added new styles for displaying error messages in search interfaces.

- **Chores**
- Removed the obsolete "Enable Cloud Indexer" feature flag; cloud
indexer behavior is now always enabled where applicable.
