send_flow_to_contacts

Run an EXISTING interactive flow for each listed contact right now, outside any trigger — as if each of them had just triggered it. Use it when the WHOLE message is the flow — its first block's text, media and buttons are what the recipient sees. To send your own custom text with buttons that run a flow on tap, prefer send_message with `buttons: [{ text, flowId }]`; it needs no wrapper flow. The flow starts at its start block for every recipient, and any `{{var|name}}` inside it resolves against that recipient's own variable context. No deploy is needed — the runtime compiles the flow on demand — but the flow must already be applied (use the ids apply_actions returned). Contacts are targeted by contactId only (from list_contacts), 1 to 50 per call. Duplicates are collapsed. Each contact is dispatched independently: one bad id fails its own row in `results` and the others still go out, so read `sent`/`failed`, not just the absence of an error. BROADCAST and OPERATION flows are rejected — a broadcast flow runs in an audience scope (send it with its broadcast) and an operation runs in system context (use run_operation). For a large audience this is the WRONG tool: create a broadcast whose flow filter selects the audience, and launch that once. Requires the send_flow_to_contact permission. NOT idempotent and not reversible — every call reaches real people again and a sent message cannot be recalled. Confirm the flow and the exact recipient list with the user before calling, and never retry a timed-out call blindly.
