Approve broadcast flow

A BroadcastFlow represents a bulk patient outreach campaign that sends the same message via SMS, email, or voice to a batch of patients, either from an uploaded contact file, an SFTP feed, or a filtered set of appointments. It tracks the full lifecycle of that campaign including upload and column mapping, optional approval review, scheduling, batched message sending, and per-row success and failure statistics, and can be organized into parent and child flows for large batches, commonly used for patient recall and other mass communications.

A BroadcastEvent records a single unit of work within a Luma broadcast flow, a bulk outbound messaging campaign sent to many patients at once (for example a recall or announcement uploaded as a spreadsheet). Each event tracks either a review action taken on the flow or the processing of one row or patient, including its current step (message queued, sent, failed, or skipped), any error encountered, and links to the associated patient and appointment.
