Fix amount rounding issue for Stripe payment fields. For example, previously, 53.57686 was rounded to 53.58 on form and in Salesforce but sent as 5.57 to Stripe. The correct value of 53.58 will now be used in all places (Salesforce, Payment Email, Stripe).
Changed the mapping id for Stripe single payment setup to Stripe's Charge Id (i.e. ch_xxx). Previously we were using Stripe's Balance Transaction Id (txn_xxx) which is incorrect. Either id can be used in Stripe search dashboard to find the related transaction.
