Idempotency-Key header for /v2/messages

Send the same Idempotency-Key on retry and we'll return the original response without double-sending. Keys expire after 24h.

Edit a Meta-approved template without losing the prior version. Roll back from the audit log if Meta rejects the change.

Fix

Webhooks now follow a stricter retry schedule (8 attempts over 6h, exponential backoff) and surface the next-retry timestamp in the dashboard.
