fix: hide cancelled/stale tournaments + allow registration on draft status

- tournaments.php: exclude cancelled tournaments (neq.cancelled filter),
  hide completed tournaments older than 3 days
- hub.js: treat 'draft' status same as 'registration' — show register
  button, green status pill, include in "registration open" filter
