fix(testing): harness calendar_font is sized like the panel's

Browse Source 
VisualTestDisplayManager built its 5x7 calendar_font / bdf_5x7_font as a
bare freetype.Face. With no size set its ascender reads 0, so BDF text
drawn with it landed 6px above where DisplayManager draws it -- entirely
off the canvas at y=0 -- and get_font_height() returned 0. Golden images
and check_plugin / dev_server previews showed text the panel does not.

Load it through load_bdf_face at the panel's 7px, so it is the very face
DisplayManager uses. Across the differential run this changes only the
cases drawn with the harness's own calendar_font (968 of 220,032), which
now match the panel's output.
