Claude 7e7d8e5325 feat: private reactions on unsealed rumors + leak prevention for private notes
Unsealed NIP-59 rumors (private replies/posts arriving in gift wraps
from other clients) were indexed as ordinary notes: public reactions,
reposts, edits, pins, OTS timestamps, labels, public bookmarks, and
deletion requests could all e-tag the private rumor id onto public
relays.

- Note.isPrivateRumor(): empty-signature discriminator (rumors are the
  only notes materialized with an empty sig; draft inners are never
  indexed as standalone notes)
- ReactionAction: reactions inherit the target's privacy — empty-sig
  targets get gift-wrapped kind-7s fanned to the rumor author, every
  tagged user, and the sender's self-copy (add-only; un-react would
  need a public NIP-09 deletion that leaks the rumor id)
- AccountViewModel.reactToOrDelete: never NIP-09-delete rumor reactions
  (also fixes the same leak for existing NIP-17 chat reactions),
  tracked-broadcast mode excluded for rumor targets
- ReactionsRow: hide reply/boost/zap on private rumors (each publishes
  a public e-tag of the target); like stays, now wrapped
- DropDownMenu/NoteQuickActionMenu: hide broadcast, edit, timestamp,
  pin, hashtag label, public bookmarks, deletion request for rumors;
  private bookmarks and block/report stay available
- Lock badge in the note header (reuses existing Lock glyph, no font
  regen needed)

Covered by ReactionActionTest (public vs rumor fan-out, jvmTest green).
