fix(gui+api): cleanup before merge

- Rename "TrovaUtensile" tab → "Cerca modello".
- Remove the "Precisione (ultime 5 detection)" stats panel and the
  "Dettagli" JSON dump from the grasp tab; keep hidden stubs so the
  existing app.js continuous-loop code doesn't null-deref.
- Add work_plane_routes to api/__init__.py imports + __all__ (consistency
  with the other routers).
- Trim the misleading "drag = pan · wheel = zoom · doppio click = reset"
  hint from the Calibrazione Piano RGB label — pan/zoom isn't wired.
- Disable wpClearBtn initially so it doesn't flash clickable before
  fetchSaved() resolves.
