Adds an admin page at /admin/draft-schedule that visualizes sport-season
draft windows (draftOn -> draftOff) as a Gantt-style timeline: Y axis is
the sport, X axis is a 6- or 12-month horizon. A warning panel highlights
sports with no open or upcoming draft window so gaps in coverage are
obvious at a glance.
- New findDraftScheduleForHorizon model query (overlap test against the
horizon, admin sport-seasons only)
- Presentational DraftScheduleGantt component with month gridlines, a
"today" marker, and status-colored bars linking to each sport-season
- Route registered in routes.ts and linked from the admin nav
- Unit tests for the model query and component
