Snap Point & Rotation Polish

Snap Points

1. New Edit Snap Points mode — drag and interact with existing snap points without switching into placement mode. Enabled by default for hosts.
2. Snap point hover now shows a clean tooltip with the attached component name, world coordinates, and tags.
3. The auto-rotation badge on canvas snap points now displays as a tiny rotating card matching the configured angle, so you can see exactly how a card will land at a glance.
4. Added Align Row and Align Col buttons to the snap point editor — instantly snaps the selected point to the same Y or X position as the nearest other snap point.
5. Removed the right-click context menu from snap points. The Remove button is now in the editor modal instead.

Rotation Dial

1. The rotation picker now shows a card shape with a pip marker instead of a crosshair/arrow, so the preview matches exactly how your component will appear on the table.
2. Dial card size increased for easier reading.
3. All 24 tick marks (every 15°) are now visible on the dial — including cardinal, diagonal, and minor intervals.
