ask_operator: multi-select + free-text fallback

ask_operator now accepts a multi: bool. when true and options is
non-empty, the dashboard renders the choices as checkboxes — operator
picks any subset, answer comes back as a ', '-joined string. when
false (default), options are radio buttons.

independent of multi, a free-text input ('or type your own…') is
always rendered alongside options so the operator is never trapped
by an incomplete list. submit merges checked options + free text into
the single 'answer' field.

schema migration: operator_questions grows a multi INTEGER column
with a one-shot ALTER TABLE on open. backward compatible — old rows
default to 0 (not multi).

prompt + mcp tool description updated; existing dashboard css for
.qform was rewritten around the new vertical layout.
