fix(client): debug console review fixes — D-088 pause, settings state, response guard

- Add D-088 Overlay pause/unpause signals to DebugConsole, wire in main.gd
  so sim does not advance while typing debug commands
- Settings dialog reads live DebugConsole.is_enabled() instead of ConfigFile
  directly, preventing checkbox/state divergence
- append_response respects disabled state — no auto-open when user disabled
  console via settings
- tp command warns on invalid z value instead of silently defaulting to 0
