system/setup: grid layout, fix mouse and font height handling

Layout: - controls 24 px high and 12 px apart, 8 px to the window border (12 at the top); text centred on the capitals of the 8x16 font - value boxes sunken, the -/+ buttons share one frame with them - checkboxes: box before the label, spread without per-item widths - group title drawn over the frame with a filled background - bevel and checkbox colours derived from the skin, no hardcoded white Fixes: - the window re-applied the mouse settings read at start, reverting changes made meanwhile; mouse is now read and applied by BOOT only - font height is clamped to 9..99, a larger ini value showed garbage and could fault on div - a GetButton result of 1 (no button) indexed rows out of bounds - hidden checkbox buttons flashed an XOR frame when pressed - skip bg_program when it is empty; drop duplicate LBA/PCI strings Assisted-by: Claude:claude-opus-5-5
