test: encode eeschema kicad-cli ground truth (currently RED)

Browse Source 
Update existing rotation/mirror assertions and add a kicad-cli-grounded
regression suite. eeschema's pin transform is verified against:
  - rotation: TRANSFORM(0,1,-1,0) for rot=90 — CCW in screen Y-down
  - mirror x: SYM_MIRROR_X = TRANSFORM(1,0,0,-1) — negates internal Y
  - mirror y: SYM_MIRROR_Y = TRANSFORM(-1,0,0,1) — negates internal X

Updated assertions:
  - test_pin_locator_y_flip: rotated cap pin 1 X 153.81 → 146.19
  - test_move_with_wire_preservation::test_resistor_rotated_90:
    pin 1 X 103.81 → 96.19
  - test_hierarchical_pad_net_map::test_90_degree_rotation:
    swapped UP_NET / DN_NET label coords

New file tests/test_pin_world_xy_eeschema_truth.py:
  - 4 parametrized diode tests via kicad-cli netlist (oracle = eeschema)
  - 2 parametrized resistor mirror tests via kicad-cli netlist
  - 3 pure-math pin_world_xy assertions for rot=90, mirror_x, mirror_y

Currently RED on rotation 90/270 (rotation direction) and mirror_x/y
(axis semantics swapped). Production fix in WireDragger.pin_world_xy
to follow.
