- First/last waypoints now only extend/shorten along their segment direction,
preventing unwanted rotation of the end boxes
- Middle waypoints remain freely draggable for direction changes
- Add default middle waypoint so new EPCs have 3 control points

- Increase EPC line width from 0.4 to 1.5 for visibility
- Increase right box stroke from 0.3 to 1.0 to match left icon stroke
- Fix right box to extend behind last waypoint (like left icon), not forward

When a symbol is mirrored, negate the horizontal drag delta and swap
the left/right handle identity so resizing matches the visual direction.
Also fixes spur handle resize with mirrored spurs.

- Remove tabs, single unified device list grouped by type
- Drop on empty space → places new symbol with device ID
- Drop on existing symbol → assigns the device ID as label
- Drop-target highlight shown when hovering over existing symbols
- Always sorted ascending by device type

Collision detection now mirrors spur trapezoid and induction arrow
vertices when the symbol is mirrored, matching the visual appearance.
Previously the collision polygon stayed unmirrored causing false
positives/misaligned collision zones.

Holding Shift while dragging locks movement to the dominant axis
(whichever has the larger delta from drag start). Works for both
single and multi-selection moves.
