Ws poc (#11293)

related to https://github.com/twentyhq/core-team-issues/issues/601

## Done
- add a `onDbEvent` `Subscription` graphql endpoint to listen to
database_event using what we have done with webhooks:
- you can subscribe to any `action` (created, updated, ...) for any
`objectNameSingular` or a specific `recordId`. Parameters are nullable
and treated as wildcards when null.
  - returns events with following shape
```typescript
  @Field(() => String)
  eventId: string;

  @Field()
  emittedAt: string;

  @Field(() => DatabaseEventAction)
  action: DatabaseEventAction;

  @Field(() => String)
  objectNameSingular: string;

  @Field(() => GraphQLJSON)
  record: ObjectRecord;

  @Field(() => [String], { nullable: true })
  updatedFields?: string[];
```
- front provide a componentEffect `<ListenRecordUpdatesEffect />` that
listen for an `objectNameSingular`, a `recordId` and a list of
`listenedFields`. It subscribes to record updates and updates its apollo
cached value for specified `listenedFields`
- subscription is protected with credentials

## Result

Here is an application with `workflowRun`
