test: add tournament schedule step definitions

Related to #7

Added step definitions for tournament schedule scenarios:
- I should see round {int} matchups
- I should see a bye round for one team
- each team should play every other team exactly once
- I click on a matchup
- I should be on the match result entry page

The active scenario (view schedule page) passes. Three wip scenarios
remain because the schedule page uses a static button without onClick
handler. The ScheduleGenerator component exists but is not integrated
into the page.
