scawful 791ebaf552 Fix menu navigation: restore original up/down behavior ...

- Keep loop counters in FindNextItem/FindPrevItem (prevents infinite recursion)
- Restore FindNextDownItem/FindNextUpItem to original logic:
  - Move ONE row, then delegate to FindNextItem if slot empty
- Fix boundary check in FindNextUpItem: use BEQ/BPL for signed comparison
  (CMP #$01 : BCS was wrong - unsigned comparison treats $FE as 254 >= 1)

The original design: Up/Down navigate rows, delegate to horizontal scan
if target slot is empty. The loop counters in horizontal navigation
prevent infinite loops when all items are empty.
