fix: resolve remaining test failures in CI

- cucumber: use 'progress' formatter in CI (not progress-bar TTY)
- csv-upload: use timestamp in player names to avoid unique constraint
- elo-ratings: delete event_participants before players (FK constraint)
- epic3-rankings: use .first() on h1/h2 locator (strict mode)
- schedule-tab: look for button instead of anchor for Schedule tab
- team-config: wait for search input before filling (step 2 async)
- tournament-edit-allowTies: check for 'Edit Tournament' not 'Tournament Name'
- epic4-tournament-creation: submit button only on step 2, add waitForSelector
