fix(cli): realign amy nutzap relays with upstream NIP-65 inbox model

Upstream reworked kind:10019 to advertise the account's NIP-65 inbox (read)
relays as nutzap-receiving relays (was outbox). Realign amy:
`cashu wallet create` now defaults nutzapRelays to a new
Context.nip65ReadRelays() (kind:10002 read relays, falling back to outbox)
instead of outboxRelays(), so amy's kind:10019 matches the Android wallet's
again. The event's publish destination (anyRelays / sendLiterallyEverywhere)
is unchanged.
