feat(payments): quick-ack + idempotent webhooks (#1664)
### Context
Stripe recommends acking webhook events ASAP with a 200. Stripe also
recommends employing event idempotency on your end. By responding
quickly, you prevent stripe from thinking the webhook failed and
retrying the event. Retrying the event in the past used to be
responsible for people getting multiple payment receipt emails. Note
that even in the case where an event processing genuinely fails, we have
a new table to let us recover from it.

Currently, recovery will be manual, but since it will be logged to
sentry we will be notified.

## Summary by cubic
Quick-ack Stripe webhooks with 200 and add atomic idempotency to stop
duplicate processing and emails. Events are persisted and processed in
the background with clear status and error tracking.

- **New Features**
- Persist each webhook in `StripeWebhookEvent` keyed by `event.id` with
full `payload` and `stripeAccountId` for recovery.
- Return 200 immediately; process in the background and track status as
`PENDING`, `PROCESSED`, or `FAILED`.
- Single-flight claim deduplicates redeliveries while `PENDING` and
after `PROCESSED`; only `FAILED` events reprocess on redelivery.
- Store `lastError` on failures; unknown webhook types ack with 200 and
are handled asynchronously.
- Webhook response includes `deduplicated: true` when a redelivery is
skipped.

- **Migration**
- Run Prisma migrations to create the `StripeWebhookEvent` table, enum,
and unique index on `stripeEventId`.

## Summary by CodeRabbit

* **New Features**
* Added persistent, idempotent Stripe webhook handling with event-level
deduplication keyed by the webhook event id.
* Webhooks are acknowledged immediately and processed asynchronously,
with automatic retry capability for failed events.
* **Bug Fixes**
* Reduced duplicate side effects from redeliveries (including preventing
repeated receipt emails) by ensuring only one successful processing per
event.
* **Tests**
* Updated and expanded integration and end-to-end coverage for
asynchronous processing, deduplication, and failure recovery behavior.
