fix: restore web terminal multiline paste by reverting scrollback to 10000

- Revert xterm.js scrollback from 0 to 10000; empirical correlation with
  bracketed-paste mode failing (each line submitted as separate command).
- Add temporary browser-console diagnostics to confirm whether xterm receives
  pi's \e[?2004h enable sequence and whether outbound paste is BPM-wrapped.
- Keep CSS scrollbar hiding and wheel-sensitivity 0 so the original scroll-jank
  fix remains effective.
