feat: add calendar widget components

Browse Source 
Add date picker and event calendar components inspired by shadcn/radix
Calendar and org-mode-agenda-cli.

Components:
- ui.calendar: Month grid date picker with navigation, today/selected
  highlighting, outside-month dimming. Pure date math utilities
  (days-in-month, day-of-week, calendar-days, etc.)
- ui.calendar-events: Event-aware grid with colored pills, horizontal
  day ticker strip with dot indicators, and agenda list view with
  grouped events by day

CSS: Token-based styling with dark mode support for event color
variants (accent/danger/success/warning). Responsive breakpoints.

All three targets supported (squint/cljs/clj). Dev pages show calendar
on its own page with interactive demos (date selection, month nav,
event grid, ticker, agenda list).

Tests: 27 new assertions covering date math, class generation,
component structure, event filtering/sorting.
