Previously the handler used kicad-skip to apply rotation and mirror.
kicad-skip has no API for (mirror x/y) on placed symbols, causing:
'NoneType' object has no attribute 'value'
Fix:
- Rewrote _handle_rotate_schematic_component to use sexpdata (same
approach as move_schematic_component) for both rotation and mirror
- Added WireDragger.compute_pin_positions_for_rotation: computes old
and new pin world positions when rotation/mirror changes at fixed (x,y)
- Added WireDragger.update_symbol_rotation_mirror: updates (at) rotation
and adds/removes/replaces the (mirror x/y) sexpdata token cleanly
- Connected wires now follow pin positions after rotate/mirror via the
existing WireDragger.drag_wires infrastructure
Tests: 10 unit tests in tests/test_rotate_schematic_mirror.py covering
update_symbol_rotation_mirror, compute_pin_positions_for_rotation, and
a handler smoke test.
