feat: redesign AutoNest dialog with grouped layout and engine selector

Rebuild the dialog from a flat layout into grouped sections: engine
selector at top, Parts group with rotation columns and summary label,
Options group, collapsible Plate Optimizer with single-field size
parsing, and a clean button bar. Adds engine sync between dialog and
toolbar.
