* Fix#4792: Add mutex protection for customSearchPath slice
The customSearchPath slice was being accessed concurrently from multiple
goroutines without synchronization, causing data races. This fix adds a
dedicated mutex (searchPathMutex) to protect all reads and writes to the
customSearchPath and searchPathPrefix fields.
Changes:
- Added searchPathMutex field to DbClient struct
- Initialize searchPathMutex in NewDbClient constructor
- Protected all customSearchPath writes in SetRequiredSessionSearchPath
- Protected all customSearchPath reads in GetRequiredSessionSearchPath
- Protected all customSearchPath reads in GetCustomSearchPath
- Fixed logging in ensureSessionSearchPath to use already-fetched value
- Updated test to initialize searchPathMutex for proper testing

- Execute RefreshConnections asyncronously
- Add connection_state table to indicate the loading state of connections
- Optimise RefreshConnections by cloning connection schemas
- Add locking to ensure only a single instance of RefreshConnections runs
- Start executing queries without waiting for connections to load, add smart error handling to wait for required connection
- Optimise autocomplete for high connection count
- Autocomplete and inspect data available before all conections are refreshed
- Update file watcher to respond to CHMOD, so thaat it pickes up deletion of file contents
