keypom/fydp-secondary-market/ silently fails on event creation batch call from keypom ticketing contract

[charleslavon]

Describe the bug On the event creation flow, when create_drop_batch is used with minimal params, no start datetime or end datetime, the create drop batch call to 1717013187496-kp-ticketing.testnet will succeed but the callback xcontract call to create_event on the marketing contract, v0.marketplace-exp.testnet (in sync with keypom/fydp-secondary-marke#feat/templates) fails with the error "FunctionCallError": { "ExecutionError": "Smart contract panicked: Start time must be before end time!" }
