## Fix resolver schema leaking between `/metadata` and `/graphql`
endpoints
### Summary
- Patch `@nestjs/graphql` to support a `resolverSchemaScope` option that
filters resolvers at both schema generation and runtime, preventing
cross-endpoint leaking
- Introduce `@CoreResolver()` and `@MetadataResolver()` decorators to
explicitly scope each resolver to its endpoint
- Move most resolvers (auth, billing, workspace, user, etc.) to the
metadata schema where the frontend expects them; only workflow and
timeline calendar/messaging resolvers remain on `/graphql`
- Fix frontend `SSEQuerySubscribeEffect` to use the default (metadata)
Apollo client instead of the core client
### Problem
NestJS GraphQL's module-based resolver discovery traverses transitive
imports, causing resolvers from `/metadata` modules to leak into the
`/graphql` schema and vice versa. This made the schemas unpredictable
and tightly coupled to module import order.
### Approach
- Added `resolverSchemaScope` to `GqlModuleOptions` via a patch on
`@nestjs/graphql`, filtering in both `filterResolvers()` (runtime
binding) and `getAllCtors()` (schema generation)
- Each resolver is explicitly decorated with `@CoreResolver()` or
`@MetadataResolver()`
- Organized decorator, constant, and type files under `graphql-config/`
following project conventions

This PR handles SSE event stream edge cases.
- When a pod restarts, the front clients have to reconnect to SSE
- When the dev server restarts or is hot reloaded, the front client has
to reconnect to SSE
- When redis server restarts or the redis key is cleared for any reason,
the server has to recreate the event stream in redis, this can happen
when navigating for example.
- Log in / log out flow
With this PR we avoid error messages in the front end due to TTL or pod
crash, we implement a resilient way of reconnecting silently.
To avoid DDoSing our servers if pods crash or a full restart of the
cluster is made, we evenly space retry attempts to reconnect from all
the clients, to avoid n clients reconnection at the same time, we use a
random wait time between 0 and a constant max wait time (set to 2 mins
for now). This is the cheapest and most effective solution, clients who
want to force reconnect have to refresh or navigate to another page.
Fixes https://github.com/twentyhq/core-team-issues/issues/2045
This PR implements SSE update events across the main components of the
application : tables, boards, calendars, show pages.
There is still work to do on other event type and on making sure
everything works fine, but this first implementation should be robust
enough to start with.
Some problems encountered along the way :
- Events are returning raw Postgres output, because they are not
normalized by the GraphQL layer, so we ended up with amountMicros as
string values, which the frontend does not like, so I implemented a
small util in our `formatResult` generic pipeline to turn amountMicros
to a number if it's a string value. We could implement other formatters
for composite fields if we see problems with events.
-`action` property was missing in SSE events, which is required by the
frontend to know what kind of event it is.

This PR is a follow-up of https://github.com/twentyhq/twenty/pull/16966
and implements a new mechanism to handle SSE events.
It creates only one event stream per browser tab, then use mutations to
tell the backend which query to listen to, without re-mounting the event
stream connexion.
Then each event that comes from this unique subscription is then
dispatched in a new JavaScript CustomEvent, per queryId, on which
specific hooks add an event listener.
This PR introduces the generic tooling as well as the handling of update
events on table.
