The _ipc_move_component and _ipc_place_component handlers were ignoring the unit field from position parameters, always treating values as mm. When inches were specified, components would be placed at 1/25.4th of the intended position. Now reads the unit field and converts to mm before passing to the IPC backend.

"""Regression test for inch-unit conversion in IPC place/move handlers.
|
|
|
|
Bug: ``_ipc_place_component`` and ``_ipc_move_component`` ignored the
|
|
``unit`` field in ``position`` and forwarded the values directly to the IPC
|
|
backend, which expects mm. Calling with ``unit="inch"`` placed the part at
|
|
1/25.4 of the intended position. The fix reads ``unit`` and converts inches
|
|
→ mm before invoking ``self.ipc_board_api.*``.
