feat(badges): add accept controls to notification card

The notification card BadgeCompose rendered the awarded badge via
BadgeDisplay (definition-only) and stopped there, so a recipient
viewing a fresh badge in their inbox had no way to add it to their
profile without navigating to the award's thread first.

Expose AcceptBadgeControls (was private inside Badge.kt) and call it
from BadgeCompose under the BadgeDisplay row when the underlying note
is a BadgeAwardEvent.

Other surfaces are unchanged:
- RenderBadgeAward (Badge feed / threads) keeps its own call to the
  same composable; behaviour is identical because the controls were
  already package-private.
- BadgeCompose has only one caller (CardFeedView, the notifications
  feed), so the new row only appears there.
