## Summary
This PR adds **metadata eventing**: when schema metadata
(objectMetadata, fieldMetadata, view, viewField, etc.) is created,
updated, or deleted, we now emit events that can trigger webhooks and
future audit logs. It also adds **actor context** (`userId`,
`workspaceMemberId`) to those events so subscribers can attribute
changes to a user or API key.
## What changed
### 1. Metadata eventing (first commit)
- **MetadataEventEmitter**
New service that emits batch events after successful workspace
migrations. Event names follow `metadata.{entity}.{action}` (e.g.
`metadata.objectMetadata.created`, `metadata.fieldMetadata.updated`).
- **MetadataEventsToDbListener**
Listens for metadata events and enqueues webhook delivery via
`CallWebhookJobsForMetadataJob`.
- **Event types** (twenty-shared)
`MetadataEventAction`, `MetadataEventBatch`, and record event types for
create/update/delete.
- **WorkspaceMigrationValidateBuildAndRunService**
Calls the metadata event emitter after running migrations so all
metadata changes (from any module) emit events from a single place.
- **Create events**
Sourced from the create action payload (`flatEntity` /
`flatFieldMetadatas`) because `fromToAllFlatEntityMaps` does not provide
a before/after diff for creates. Update/delete events still use the
fromToAllFlatEntityMaps comparison.
### 2. Actor context (second commit)
- **MetadataEventEmitter**
Accepts optional `actorContext` (`userId`, `workspaceMemberId`) and
includes it on emitted batch events.
- **WorkspaceMigrationValidateBuildAndRunService**
Passes `actorContext` from the request into the metadata event emitter.
- **Metadata resolvers & services**
All metadata modules resolve `@AuthUser({ allowUndefined: true })` and
`@AuthUserWorkspaceId()` and pass `userId` and `workspaceMemberId`
through to the migration/event pipeline. Both are optional so
API-key–authenticated requests (no user) still emit events without a
user identity.
