Feat: add bounding box and courtyard info to component queries (#163)

Browse Source 
Components now include boundingBox (min/max X/Y, width, height) in
get_component_list and get_component_properties responses. The SWIG
get_component_properties also includes courtyard dimensions when the
footprint defines a courtyard layer.

SWIG backend uses GetBoundingBox() and GetCourtyard(). IPC backend
tries get_item_bounding_box(), then pad-extent fallback, then falls
back to SWIG backend data when available. This ensures bounding box
data is present regardless of which backend handles the query.
