Eric Allam c0b84595a3 feat(webapp): hosted webhook ingress, delivery pipeline, and dashboard (#4344)
## Summary

The server half of hosted webhooks: the public ingress endpoint,
signature verification, the delivery pipeline (Postgres partitioned
storage + ClickHouse for ordering), the in-app partition manager, the
HTTP API, and the dashboard (Deliveries, Endpoints, and the in-app test
console).

The public SDK and docs half is #4537. That PR carries the user-facing
API (`webhook()`, `chat.event` / `chat.channels`, the
`@trigger.dev/slack` connector) and builds on the shared
`@trigger.dev/core` schemas that ship here.

## Shipping behind a flag

A `WEBHOOK_ENABLED` env var (default off) gates the public ingress route
and the engine worker plus partition cron, so merging and deploying this
changes nothing in production until it is flipped on per environment.
The dashboard is separately gated per org by the `hasWebhooksAccess`
feature flag.

## Note on packages

This PR includes the `@trigger.dev/core` schema additions the server
compiles against, but carries no changeset. Core is not consumed
independently of the SDK, so it is released together with the SDK via
#4537. Keeping its changeset off `main` means no release cut from `main`
publishes it early.

The event bodies are normalized (transport and signature headers stripped, routing headers kept) into this package's SampleRecord shape by src/ingest.ts. Signatures are not stored; the console signs each body with the target endpoint's own config at send time.
