Platform admin: create a booth scan link and PIN

Returns the link token and six digit PIN once; only hashes are stored. The link lets promoters validate and redeem this merchant's (or one outlet's) vouchers on a phone without signing in, after entering the PIN once per device. The default end is the last collect-by date of the merchant's published offers; a later date may be set (up to 399 days). At most 20 live links per merchant. Needs a recent sign-in (last 30 minutes).
