vote_fetcher was missing from Celery's include list (task not registered with
workers) and had no beat schedule — votes only fetched on-demand when a user
visited a bill's votes page. Stanced bills (pocket_veto/pocket_boost) never had
votes fetched, leaving the alignment page blank.
Add fetch_votes_for_stanced_bills nightly task (4:30 AM UTC) that queues
fetch_bill_votes for every bill any user has stanced but has no stored votes.
Register vote_fetcher in the include list and add it to the polling queue route.
