Raphaël Bosi 2455c859b4 Add SSE for metadata and plug front components (#17998)
Create the necessary tooling to listen to metadata events and plug it to
the front components. Now we have a hot reload like experience when we
edit a component in an app.

## Backend

- Split `EventWithQueryIds` into `ObjectRecordEventWithQueryIds` and
`MetadataEventWithQueryIds`
- Publish metadata event batches to active SSE streams in
`MetadataEventsToDbListener`

## Frontend

- Create a metadata event dispatching pipeline: SSE metadata events are
grouped by metadata name, transformed into
`MetadataOperationBrowserEventDetail` objects, and dispatched as browser
`CustomEvents`
- Add `useListenToMetadataOperationBrowserEvent` hook for consuming
metadata operation events filtered by metadata name and operation type
- Rename `useListenToObjectRecordEventsForQuery` to
`useListenToEventsForQuery`, now accepting both
`RecordGqlOperationSignature` and `MetadataGqlOperationSignature`
- Implement `useOnFrontComponentUpdated` which subscribes to front
component metadata events and updates the Apollo cache when the
component is modified
- Add `builtComponentChecksum` to the front component query and appends
it to the component URL for browser cache invalidation

Does the world need another CRM?

We built Twenty for three reasons:

CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.

A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.

We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
