Claude 12ed86627c feat(nutzap): fold nutzaps into reaction-row zap counter + icon highlight
Phase 0 (small fix): sendNutzap was async-launched with no success
callback, so after tapping the teal cashu chip in the zap picker
the popup vanished and the user saw no feedback for the 1-2 seconds
it took the swap + publish to complete. Add a "Cashu zap sent —
Sent N sat(s) via cashu" toast on success, matching the lightning
zap's progress feedback in spirit.

Phase 1 (foundation): NIP-61 nutzaps attach to their target note
the same way LN zaps and onchain zaps do, contributing to the
reaction-row total and the "you-already-zapped" icon highlight
without any UI-layer change.

Pieces:

- NutzapEvent.claimedSatsTotal() in quartz parses the sender-
  claimed sat sum from the proof tags once, leniently (a single
  malformed proof contributes 0 rather than throwing). The
  recipient wallet still verifies proofs against the mint at redeem
  time; this is the trusted-claim total for display.

- Note.nutzaps: Map<HexKey, NutzapEntry> on the canonical commons
  Note, parallel to onchainZaps. NutzapEntry carries the source
  kind:9321 note (sender = source.author) and the pre-parsed
  claimedSats. Volatile because writes happen on applicationIOScope
  and reads happen on the Compose main thread.

- updateZapTotal() now sums nutzap claimedSats into zapsAmount, so
  the existing ObserveZapAmountText composable in ReactionsRow
  picks up cashu without code change.

- hasZapped() and the suspend isZappedBy() extended to detect
  nutzaps from a given user. ReactionsRow's calculateIfNoteWasZap-
  pedByAccount path therefore highlights the bolt orange for cashu
  zaps the same way it does for lightning.

- LocalCache previously routed NutzapEvent through
  consumeRegularEvent, which would add it as a *reply* to the
  e-tagged note via computeReplyTo. computeReplyTo gains a
  NutzapEvent case returning the linked event ids, and a dedicated
  consume(NutzapEvent) function attaches via addNutzap instead of
  addReply.

The "list" merge across LN + cashu + onchain that the user floated
is deferred — three separate collections with different shapes
(zap pair, onchain entry, nutzap entry) are kept; only the
aggregates and queries are unified. That's enough for the
reaction-row UX and avoids touching every iteration site at the
call layer.

Coming next: notifications (NotificationFeedFilter + a cashu-icon
variant of ZapUserSetCard) and the dedicated cashu row in
ReactionDetailGallery modeled on OnchainZapGallery.
