fix(interest-sets): consume kind 30015 locally + empty-state polish

- LocalCache.consume dispatcher now handles InterestSetEvent via
  consumeBaseReplaceable, so the event created by the user is stored
  and flows through newEventBundles → interestSets.newNotes → listFeedFlow
  refresh. Without this, the just-signed event sat in the sendMyPublicAndPrivateOutbox
  call but the UI never saw the update.
- List screen: icon + centered text for the empty state and dividers
  between rows.
