Adds ClickHouse to Data Sources over its HTTP interface (HTTP/HTTPS, SSH tunnels, session settings, server-side cancellation): browse databases, tables and columns, inspect DDL, run queries and EXPLAIN plans, with ClickHouse dialect completion. Table data stays read-only and manual transactions are rejected, since ClickHouse keys are not unique and HTTP has no transactions.
Results are streamed as JSONCompactEachRowWithNamesAndTypes and parsing stops at the row limit, because result_overflow_mode=break still returns a whole block; errors show only the server's "Code: …" message, including failures raised mid-stream.
Fixes#862

Run oxfmt once over the whole repository (formatting only, no logic changes) and add `pnpm format:check` to the frontend CI job so unformatted code no longer builds up. `.oxfmtrc.json` now skips the generated theme docs, test fixtures and code blocks inside Markdown.
