Dialogs for joints, sheet metal and plastic

ASSEMBLE panel (SOLID, SHEET METAL, PLASTIC): New Component, Joint, As-built Joint, Joint Origin,
Rigid Group, Drive Joints, Motion Link, Interference. Joint origins are picked by hovering:
faces snap to their centre (round faces to the centre of the nearer end), edges to their middle
(round edges to their centre), vertices to themselves, shown as glyphs with their z axis. The
Joint dialog has the motion type, angle, offsets X/Y/Z, flip, per-value limits and Animate (the
preview plays the motion); joints and drives preview on the placed model (world states).
Drive Joints moves live with a slider. Interference lists the overlaps and shows them red.
Joints appear in the timeline and in a Browser Joints folder (edit, drive, suppress, delete).

SHEET METAL tab in Fusion's layout: Flange (base, edge or contour, from the picks; height arrow
on the canvas), Hem, Unfold, Refold, Convert to Sheet Metal, Sheet Metal Rules (rule manager),
Create Flat Pattern (flat view with up/down bend lines, bend table, DXF export).

PLASTIC tab with SETUP: Boss, Lip/Groove, Snap Fit, Rest, Manage and Assign Plastic Rules; Rib,
Web and the shared solid commands on the tab.

Every feature dialog has live preview, Edit Feature and pre-selection; icons drawn in code.
Toolbar layout per tab in workspace.rs; tests for the dialog to command mapping.
