Convert sale to under contract

Converts a pre-contract sale to under-contract status. This endpoint only works when the sale is currently in Pre-Contract status; otherwise it returns 422. Conversion payload validation follows managed-field requirements and includes property/source/date/price rules (for example: required source/otherSource combinations, required contract acceptance or closing fields when configured, acceptance date not in the future, and sale price constraints).
