feat: rewrite bootstrap, fix CloudKit sync, update canonical data, and UI fixes

- Rewrite BootstrapService: remove all legacy code paths (JSONStadium,
  JSONGame, bootstrapStadiumsLegacy, bootstrapGamesLegacy, venue aliases,
  createDefaultLeagueStructure), require canonical JSON files only
- Add clearCanonicalData() to handle partial bootstrap recovery (prevents
  duplicate key crashes from interrupted first-launch)
- Fix nullable stadium_canonical_id in games (4 MLS games have null)
- Fix CKModels: logoUrl case, conference/division field keys
- Fix CanonicalSyncService: sync conferenceCanonicalId/divisionCanonicalId
- Add sports_canonical.json and DemoMode.swift
- Delete legacy stadiums.json and games.json
- Update all canonical resource JSON files with latest data
- Fix TripWizardView horizontal scrolling with GeometryReader constraint
- Update RegionMapSelector, TripDetailView, TripOptionsView UI improvements
- Add DateRangePicker, PlanningModeStep, SportsStep enhancements
- Update UI tests and marketing-videos config
