feat(webhooks): durable retrying delivery for final webhooks (#478)
* feat(webhooks): durable retrying delivery for final webhooks

Final webhook nodes were fired inline with a single best-effort httpx POST
(run_integrations._execute_webhook_node). On a transient error the failure was
swallowed at three levels, so ARQ never retried and the final call report was
permanently lost -- leaving downstream receivers stuck (e.g. a CRM showing a
call as still "in conversation").

Replace the one-shot POST with a durable, idempotent delivery pipeline modelled
on the campaign retry pattern (persisted row + scheduled_for + bounded attempts):

- New webhook_deliveries table (WebhookDeliveryModel) is the source of truth.
  Payload is rendered once and frozen so retries are deterministic; secrets are
  not stored -- the credential is referenced by uuid and re-resolved at send time.
- run_integrations now persists a delivery row and enqueues deliver_webhook with
  a deterministic ARQ job id instead of sending inline.
- deliver_webhook (new ARQ task) sends the request and:
    * 2xx            -> succeeded
    * transient      -> retry with capped exponential backoff (RequestError /
                        5xx / 408 / 425 / 429), up to max_attempts then dead_letter
    * permanent 4xx  -> dead_letter immediately (no pointless looping)
  It is idempotent: a non-pending delivery is a no-op, so a duplicate enqueue or
  sweeper re-injection can't double-send.
- sweep_webhook_deliveries cron (every 5 min) re-enqueues overdue pending
  deliveries so nothing is lost to a worker restart / Redis flush.
- Stable X-Dograh-Delivery-Id / Workflow-Run-Id / Attempt headers let receivers
  dedupe retried deliveries.
- enqueue_job now forwards ARQ job options (_job_id, _defer_by); failures log
  repr(e) so empty-message errors like ConnectTimeout are diagnosable.

Config via DEFAULT_WEBHOOK_DELIVERY_CONFIG (env-overridable): max_attempts=5,
base_delay=30s, max_delay=600s, timeout=30s.

Tests cover payload rendering, persist+enqueue, success, transient retry,
retryable 5xx, permanent 4xx dead-letter, attempt exhaustion, and idempotency.
Migration verified to apply/rollback against Postgres; table/enum/indexes confirmed.

* fix(webhooks): atomic claim, safe success-recording, sweep paging, migration cleanup

Address review feedback on the webhook delivery pipeline:

- deliver_webhook now atomically claims a delivery (conditional UPDATE that
  leases scheduled_for) before sending, so concurrent ARQ executions can't
  double-send (the prior status=='pending' read was non-atomic).
- Recording success is moved out of the dead-letter try-block: if the receiver
  accepted the payload (2xx) but the success DB-write fails, the row is left
  pending for the sweeper to reconcile instead of being dead-lettered.
- The sweep keyset-paginates by id so a backlog over the page size is fully
  drained, and logs the true re-enqueued total.
- Migration downgrade drops the enum via op.execute(DROP TYPE IF EXISTS ...)
  instead of the deprecated op.get_bind().

* fix(webhooks): idempotent delivery creation and drop secret custom headers

Address the remaining review feedback:

- Add a (workflow_run_id, webhook_node_id) unique constraint and make
  create_webhook_delivery a get-or-create returning (delivery, created). A
  retried run_integrations now reuses the existing row instead of creating and
  sending a duplicate final webhook; only a freshly-created row is enqueued.
- Stop persisting secret-looking custom headers (Authorization, X-API-Key,
  Cookie, ...) in plaintext on the delivery row: they are dropped with a warning
  pointing at the credential store (which is re-resolved securely at send time).
  Non-secret custom headers are unaffected.

* fix(webhooks): harden idempotency key, secret-header match, sweep reclaim id

Address follow-up review feedback:

- webhook_node_id is now NOT NULL so a NULL can't slip past the
  (workflow_run_id, webhook_node_id) unique constraint and create duplicates.
- Secret-header filtering matches normalized markers (auth/token/secret/cookie/
  api-key/...) instead of an exact name list, catching variants like
  X-Custom-Auth-Token while leaving benign headers (e.g. X-Idempotency-Key).
- The sweeper re-enqueues with a reclaim-specific job id (the lease timestamp)
  so reconciling a delivered-but-unrecorded row isn't deduped against the
  original attempt's already-completed ARQ job. The atomic claim still ensures
  at most one send.

* fix(webhooks): scope delivery rows to workflow org
