fix(app-showcase): surface Task Detail quick actions in the record_section bar (#2082)

The Task Detail page's `record:quick_actions` bar (location: 'record_section')
names `showcase_mark_done` + `showcase_log_time`, but neither action declared
the `record_section` location, so the engine location-filtered them out and the
drawer showed the dev placeholder "record:quick_actions — no actions configured".
Add `record_section` to both actions' locations, mirroring the platform's own
sys-user pages, so the Mark Done / Log Time buttons render.
