The 'update' notification formatter unconditionally read
details['status']['from']/['to'], so any title/priority/description/
category/type/visibility-only edit fell through to '?' on both sides
and produced a broken "changed status on #123: ? → ?" title regardless
of what actually changed. Now it branches on the delta shape actually
present: the flat {field, from, to} shape used for visibility changes,
then each per-field {from, to} delta in priority order, falling back
to a generic "updated ticket" message only if none match.
