WB.10 Civilcraft: Add basic drafting tools. Snapping on elements. Move , Copy Rotate etc....

Drawing tools needed in Civilcraft. Snaps are need when drawing parcels, alignments and pads. All menu dialogs with coordinates show should have a button to allow users to snap to a point in the drawing. Entering N,E,Z manually is very , very time consuming and not used by any major civil design programs anymore. Points and bearings should have a pick button on all menus. Tangents should have two pick button to define the bearing with two points.

**Built:** Built in /lab 2026-11-06 (civil-snap-09). Snaps: the Alignment, Pad, Parcel, Mass, Feature line, Measure, Boundary and Catchment tools and a dragged PI or corner snap to survey points and to PIs, pad / parcel / mass corners, feature-line vertices and structures within 10 px (a marker with a label and the E, N; Alt = free). A crosshair Pick button sits beside a PI's northing, every corner's northing and the move / rotate blocks. Tangent from two points under the PI table.
