demo: contractor links — respect the /lakehouse path prefix

J reported https://devop.live/contractor?name=3115%20W%20POLK%20ST.%20LLC
returned 404. Cause: the anchor href was a bare /contractor, which on
devop.live routes to the LLM Team UI (port 5000) at the main site root,
not the lakehouse mcp-server (which lives under /lakehouse/*).

Every page that renders a contractor link now uses the same prefix
detector the dashboard already had:

  var P = location.pathname.indexOf('/lakehouse') >= 0 ? '/lakehouse' : '';

Files updated:
- search.html: entity-brief anchor + preview anchor → P+/contractor
- console.html: permit-card contractor list → P+/contractor
- contractor.html: history.replaceState + back-link + the
  /intelligence/contractor_profile fetch all use P prefix. The page
  is reachable at /lakehouse/contractor on the public URL and bare
  /contractor on localhost; both work without further config.

Verified:
  https://devop.live/lakehouse/contractor?name=3115%20W%20POLK%20ST.%20LLC
    → 200, 29.9 KB, full profile renders. Contractor has 1 permit on
    file (a small LLC), 1 geocoded so the heat map plots one marker.
