The active identity drives the single live gift-wrap subscription and every
send/display, and every identity redeems into the ONE shared grin balance.
Switching reuses the rotate/import stop-wait-start machinery: it verifies the
wallet password by unlocking the target BEFORE any teardown (a wrong password
never strands the wallet with no running identity), gates on no in-flight
send, tears down the service and stands a fresh one on the target key against
the SAME shared store (so processed-dedup carries across and nothing double
redeems), and moves only the active pointer (identity.json is never
overwritten). The catch-up now looks back from when THIS identity last
listened, so a payment that arrived while it was dormant is fetched and
redeemed on switch-in; the service surfaces a syncing state and a count of
payments redeemed during that catch-up for a "you were paid while away" cue.
TxNostrMeta gains recipient_pubkey (serde-default empty = primary) to tag
which front door a payment used, for per-identity activity and a later
accounting split. Wallet gains nostr_identities / add_nostr_identity /
switch_nostr_identity, init_nostr adopts the held-identity index with legacy
migration, and a wallet-password change now re-encrypts every held identity
through the same NIP-49 path. Only the active nsec is ever decrypted in
memory; the rest stay encrypted at rest.
