CUTSCENE_SAVE_DEVICE_CHECK and CUTSCENE_SAVE_LOAD_ALL_SLOTS wrap the
existing device-lookup/slot-load calls and jump straight to a
success/failure marker, and CUTSCENE_MODAL_OPTIONS_ONE/TWO do the same
for one/two-option modals, removing the need for a hand-written
goTo-only callback per use. Main menu's "Start Game" now runs a
cutscene (mirroring the initial scene's save-check flow) that loads all
slots before opening the load-game picker, retrying on error; the
initial scene's own device check is migrated onto the same items.
Backing out of the main menu now returns to the initial scene.
