gsxdsm c7266b7fbd fix(FN-000): restore iOS terminal input by full-covering helper textarea ...

On iOS Safari/PWA, tapping the terminal opened the keyboard but typed
keys produced no output. Focus landed on a 1×1 opacity-0.01 helper
textarea overlapped by the xterm canvas, and capture-phase gesture
handlers re-focused on every tap — a combination iOS silently drops
input events on.

- On touch-primary devices, expand .xterm-helper-textarea to cover the
  entire terminal surface (100% × 100%, opacity 0, z-index 2) via
  @media (hover: none) and (pointer: coarse). Taps land on the
  textarea directly, so iOS grants keyboard + input events natively.
- Desktop keeps the 1×1 rule so xterm's canvas-level drag-to-select
  and mouse tracking continue to work.
- Revert onPointerDownCapture/onTouchStartCapture/onClickCapture back
  to bubble-phase onPointerDown/onTouchStart; capture phase was
  confusing iOS's focus attribution and is no longer needed now that
  taps reach the textarea directly.
