feat(ST-n1csfo4j): handleAllDone + AlertDialog + Alles-op-done knop in sprint-afronden-dialog

Voegt handleAllDone toe (roept setAllSprintTasksDoneAction aan en zet alle
per-story decisions op DONE in de UI), een bevestigende AlertDialog en een
'Alles op done'-knop bovenaan de story-lijst in de sprint-afronden-dialog.
Voegt setAllSprintTasksDoneAction ook toe aan actions/sprints.ts omdat die
branch nog niet op main staat.
