feat(dev_tools): enhance SQL Query Tool — clear, copy, history, edit, hardening

UI: add Clear and Copy-to-clipboard (TSV) buttons, an in-page Recent
Queries pane (localStorage, capped at 20, de-duped) and a pencil-edit
flow for saved queries with a dedicated SQL field in the modal.
Bind Ctrl/Cmd+S to open the save modal (or edit the active saved query).

Backend: harden validate_query with a multi-statement guard that
respects string literals + comments. Stop swallowing record_query_run
errors silently — log via logger.exception so failures show up.
