refactor(native): replace runOnJS with scheduleOnRN and custom timeAgo with date-fns

- Swap `runOnJS` for `scheduleOnRN` from `react-native-worklets` in
  gesture handler `.onEnd()` callbacks (HeroBanner, PosterCard)
- Delete custom `timeAgo` util; use `date-fns` `formatDistanceToNow`
  in integration status strings
- Enhance person detail screen: formatted birth date with age/death
  calculation, place of birth with MapPin icon, department label
  mapping, CalendarIcon for dates
- Fix `ExpandableText` truncation detection by measuring line count
  on a hidden full-text node rather than the clamped one; add
  `actionColor` prop so title accent color can theme the toggle
- Polish PosterCard metadata row: remove icon opacity, tighten gaps
