feat(ui): iOS-parity timestamps, NIP-05 badge, and follow badge (#624)

Three polish items to match iOS across post cards, notifications, quoted
notes, and avatars.

- Timestamps: compact day suffix ("1d".."6d") instead of the word
  "yesterday" at one day old, consistent with the existing s/m/h tiers;
  falls back to the absolute date only past a week. PostCard, GalleryCard,
  RichContent quoted-note preview, NotificationsScreen.
- NIP-05 badge: scalloped Icons.Default.Verified seal (points) instead of
  a plain circle; icon-only (no handle text) next to the username
  everywhere it appears — feed, threads, comments, galleries, and quoted
  notes. Handle text stays reserved for the profile screen.
- Follow badge: orange (primary) circle with a checkmark that flips with
  the color scheme — black in dark mode, white in light mode — derived
  from the active surface luminance so theme presets stay correct.
