User asked for "2 punti" — replace the drag-to-rectangle interaction with
two discrete clicks: first click places corner A (cross marker), second
click defines the rectangle, third click starts a new selection.
Rectangles smaller than 10×10 px are rejected. Status chip guides the
flow.

Direct fetch to http://localhost:8877/api/rgb fails from the browser due
to CORS (page is served from :8890). Switch to /api/calibration/rgb.jpg
which presa-mano already proxies same-origin.

New tab replaces the removed Servo Visuale. Shift+drag on the RGB image
defines a rectangle, 'Calcola piano' calls POST /api/work_plane/fit and
renders the plane + a colored scatter in 3D. Adjusting the offset slider
re-colors the scatter client-side. 'Salva piano' persists; 'Rimuovi piano
salvato' clears.
