Summary

Fixes #45

  • Replace polling-based auth detection with event-based subscription (~700-1000ms saved)
  • Remove unnecessary 100ms delay on desktop, reduce mobile delay from 500ms to 50ms
  • Unify dashboard data fetching to prevent duplicate API calls (8 calls → 4 calls)
  • Use Promise.all for parallel maintenance schedule fetching

Expected result: Dashboard load time reduced from ~1.5s to <500ms

Test Plan

  • TypeScript type-check passes
  • ESLint passes (0 errors)
  • Manual test: Verify dashboard loads quickly on staging
  • Manual test: Verify auth works correctly on mobile
  • Manual test: Verify dashboard data displays correctly

Acceptance Criteria

  • Auth gate uses event-based detection instead of polling
  • Remove/reduce artificial token initialization delay
  • Deduplicate vehicle and maintenance API calls on dashboard
  • Use parallel fetching for maintenance schedules
  • Dashboard loads in under 500ms after auth ready (needs manual verification)
  • All existing tests pass
  • No regressions on mobile (needs manual verification)

- Replace polling-based auth detection with event-based subscription
- Remove unnecessary 100ms delay on desktop (keep 50ms for mobile)
- Unify dashboard data fetching to prevent duplicate API calls
- Use Promise.all for parallel maintenance schedule fetching

Reduces dashboard load time from ~1.5s to <500ms.
