Subject: [PATCH] goblin: show the paid/used identity on the transaction detail
 view

The transaction receipt now has an Identity row telling the user which of the
wallet's held nostr identities was active when that payment was received or
sent. It uses the identity recorded on the transaction (TxNostrMeta's
recipient_pubkey), not a reconstruction, and falls back to the primary
identity for pre-feature rows. It shows the NIP-05 name when the identity has
one (any domain), otherwise a truncated npub, and is always shown on the
detail view (no clutter there whether the wallet holds one identity or many).
The activity list rows are unchanged. New goblin.receipt.identity string added
in all six locales.
