Fix: Downgrade Monaco Editor to 0.52.2 to restore keyboard paste functionality

Problem:
Users reported that keyboard paste (Ctrl+V / Cmd+V) stopped working in all Monaco editors (Query Editor, Document View). Copy still worked, and context menu paste worked, but keyboard shortcuts failed silently.

Root Cause:
Monaco Editor 0.53.x/0.54.x introduced a regression affecting keyboard paste in webview environments. The same issue was reported and fixed in vscode-cosmosdb (#2843).

Solution:
Downgraded monaco-editor from ~0.54.0 to ~0.52.2, following the same fix applied in vscode-cosmosdb#2847.

Closes #435

Follow-up:
Issue #469 tracks upgrading to Monaco 0.56.0 once released, which should include fixes for clipboard issues.

• Dependency management:
