Add pointer-based gesture handling to the calendar for lateral navigation
(drag/swipe left/right) and pinch-to-zoom between temporal layers. Also
fix dark mode across 30+ canvas shape components by replacing hardcoded
white backgrounds and input styles with --rs-* CSS custom property
references (with light-mode fallbacks).

- Shape drag now accounts for canvas CSS transform scale so elements
track the cursor correctly at all zoom levels
- Collision resolution uses minimum penetration depth algorithm instead
of movement-direction bias, preventing elements from flipping sides
- Replaced all \uD83D surrogate pair escapes and \u00D7/\u276E/\u276F/
\u2022 escapes with actual Unicode characters across 60+ files
