Templates previously referenced specific sports seasons (e.g. "NFL 2026"), requiring
admins to create a new template every year. Templates now reference sports directly
(e.g. "NFL") and resolve to the currently-draftable season at league-creation time.
- Remove `year` field from season_templates table
- Replace `sportsSeasonId` FK with `sportId` FK in season_template_sports
- applySportsFromTemplate now resolves each sport to its active draftable season
- Admin template UI updated to manage sports (not specific seasons)
- sports-data-sync export/import updated to the new sport-centric format

Every route now exports a meta function so the browser title bar reflects
the current page. Static pages use fixed titles; dynamic pages pull names
from loader data with a sensible fallback (e.g. league name, sport season
name, team name).
Titles follow the pattern "Page Name - Brackt" for user-facing routes and
"Page Name - Brackt Admin" for admin routes.
