James Dansereau 72af96cf0d Options overlay: native gamepad support (Select / D-pad / A / B / Start).
Controller-only machines (Steam Deck) had no way to open or navigate the
F10 options overlay -- it was keyboard+mouse only. Now:

- Select (BACK) rising edge toggles the overlay, tracked across both the
  open and closed poll paths (padSelectPrev) so a held button cannot
  re-toggle on the transition. BACK is read nowhere else in the port.
- While open, D-pad or left stick up/down moves the selection, A/X step
  forward (the Enter equivalent), B/Y step back, Start closes. The gamepad
  bits are OR-ed into the existing keyboard edge logic, so repeat/clamp/
  scroll behaviour is identical; input.c already swallows pad 0 while the
  overlay is open, so nothing reaches the game.
- inputPadButton/inputPadAxis accessors expose raw SDL pad state to the
  overlay (unaffected by our logic-layer swallow).

Smoke-tested headless with GE_OPTIONSOVERLAY=1 and no pad attached.
