Escape does not close the "Save query" dialog #32

Pressing Escape in the Save query dialog (opened with Cmd/Ctrl+S from the SQL editor) does not close it. The dialog is opened programmatically from Monaco, and the default escape-to-close does not fire reliably through that focus path in the WebKit/Tauri webview.

Expected
Escape closes the Save query dialog.

Addressed by #22.
