Poem

🐰 A field hops away into the past,
While durationInMinutes arrives at last!
The schema grows stronger with each new note,
As types and specs dance in their coat.

- Around line 2843-2846: Update the OpenAPI schema for
CallRequestUpdatePayload.durationInMinutes to enforce the same lower bound as
server validation by adding "minimum: 1" (keep "format: int64"); ensure the
schema field named durationInMinutes under CallRequestUpdatePayload reflects
this change and verify the server-side check in modules/entity/utils.bal that
uses stateKey == 2 still matches the contract.
