fix(autoping): align warning command with on|off

The warning toggle uses _cmd_set_boolean_preference (accepts on|off) and the
subcommand is "warning", but the help syntax, console status lines and warning
text advertised "warning enable|disable" and "/autoping warn", none of which
work.

- cmd_defs: document "/autoping warning on|off"
- console: show "(/autoping warning)" in the status lines
- iq: point the warning text at "/autoping warning off"
- cmd_ac: register "warning" and complete on|off via a dedicated
  _autoping_autocomplete (moved off the generic single-level table)
