fix(mcp-scan): report single-server scans even with zero tools

Remove the skip-if-no-tools guard. URL-less servers (e.g. Claude desktop OAuth
remote connectors, which can't be tool-scanned) must still report so the control
plane can create metadata and fingerprint/group them. The backend already
upserts metadata regardless of tool count.

Behavior change: a single-server scan that yields 0 tools now always POSTs.
