widget: show only live goals, crop finished to a one-line summary

Completed goals were listed in file order, so done goals pushed the
active/open work down the widget. Now show active+open in full and
collapse done/cancelled into a single muted '✔ N done  ✗ M cancelled'
line. Full history stays in goals.md and the ## Log.
