Root cause the user hit: NWC doesn't publish zap receipts, and neither does
bitvid — per NIP-57 the recipient's LNURL server publishes the kind-9735
receipt. Custodial providers (Strike) routinely don't, so a paid zap leaves
NO on-relay record to count, and the in-memory optimistic bump vanished on
reload → zapped videos showed 0 and never rose on Most Zapped.
Add a durable local ledger (localStorage bitvid:sentZaps:v1) of the user's
OWN sent zaps, seeded into the store's optimistic layer at construction so
the badge + Most-Zapped rank survive reloads with no receipt. Reconciliation:
when a real 9735 receipt for a pointer later appears on relays, the relay
becomes authoritative and that pointer's ledger entry is pruned, so a
receipt-publishing recipient never double-counts. ingestLocalZap writes the
ledger; runBatch prunes it.
Live-verified: card badge 0 -> 4.3K sats on send, still 4.3K after a full
page reload, ledger present in localStorage. Tests cover persist-across-
reload and prune-on-real-receipt.
