ps1: fit whole cover in ICON0 frame, show full PIC0 title

- ICON0: scale the cover to fit the case slot (no cropping), centred with
  the frame's dark background behind the letterbox bars.
- PIC0: shrink the title font until the full name fits instead of cutting
  it with an ellipsis (falls back to eliding only below 10px).
