Pay Sare Till From Kibeti
Sends money from the caller’s Kibeti wallet to a Sare till. destinationWalletId must be the till’s BUSINESS wallet id. Kibeti has no Choice account of its own, so this is a real cross-account movement: confirm it with Confirm Kibeti Send Money (Request OTP), then Verify Kibeti Send Money OTP - the same Choice-call-then-OTP pipeline as a P2P transfer.
