Update Call is moving to ended calls only

• Update Call

• override_dynamic_variables (on Update Call)

• For ongoing (live) calls: Update Live Call (PATCH /v2/update-live-call/{call_id}). Dynamic variable overrides go under fields_to_override.override_dynamic_variables; the same request can also override metadata and data_storage_setting, and control the live agent via call_control (trigger_response, additional_context).
• For ended calls: continue using Update Call to update metadata, data_storage_setting, and custom_attributes.

1. Update Call will only accept requests for calls that have already ended. Requests targeting ongoing calls will be rejected.
2. Updates you make through Update Call — including data_storage_setting — will take effect only on ended calls, not on ongoing calls.
3. The override_dynamic_variables input on Update Call will no longer be accepted.
4. To change settings on an ongoing call (dynamic variables, data_storage_setting, etc.), use the Update Live Call API instead.

• If you call Update Call on an ongoing call to change dynamic variables, switch to Update Live Call and move the values under fields_to_override.override_dynamic_variables.
• If you call Update Call on an ongoing call to change data_storage_setting, switch to Update Live Call; through Update Call, data_storage_setting takes effect only after the call ends.
• If you call Update Call on an ended call, no change is needed for metadata, data_storage_setting, or custom_attributes. Remove override_dynamic_variables from those requests — it has no effect on an ended call.
