Kyle Pope 2ab7121e42 Phase 4: Frontend performance optimizations
- AW-2: Scope calendar events fetch to visible date range via start/end
  query params, leveraging existing backend support
- AW-3: Reduce calendar events poll from 5s to 30s (personal organiser
  doesn't need 12 API calls/min)
- AS-4: Gate shared-calendar polling on hasSharedCalendars — saves 12
  wasted API calls/min for personal-only users
- AS-2: Lazy-load all route components with React.lazy() — only
  AdminPortal was previously lazy, now all 10 routes are code-split
- AS-1: Add Vite manualChunks to split FullCalendar (~400KB), React,
  TanStack Query, and UI libs into separate cacheable chunks
- AS-3: Extract clockNow into isolated ClockDisplay memo component —
  prevents all 8 dashboard widgets from re-rendering every minute
