Claim a voucher to the user's wallet
Adds a wallet-flow voucher to the user’s saved list. Required before the same voucher can be redeemed at an outlet. Idempotent — calling twice returns the original claim row with HTTP 200. Only works for vouchers whose claimFlow is WALLET; instant-flow vouchers are redeemed directly without claiming first. If the user’s partner has a restricted scope, claiming an out-of-scope voucher returns 403.
