fix: visible Liquid Glass again, group icon on group events, week today colour

- Liquid Glass: the calendar content now scrolls underneath a translucent
  safeAreaInset bar (real glass look restored) while the inline title stays
  reliable — toggling Liquid Glass is visibly different again.
- Group events are prefixed with the group's own emoji icon (from group
  settings) instead of a generic people glyph, so they're recognisable.
- Week view: today's column header now uses the configured "today" colour
  instead of the accent colour (matches the current-time line).
