## 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

# Introduction
related to https://github.com/twentyhq/core-team-issues/issues/1833
In this PR we're starting the sync-metadata and standardIds deprecation
by introducing `twenty-standard` application that will regroup every
standard object such as company and opportunities. But also the
`custom-workspace-application` which is an app created at the same time
as a workspace and that will regroup everything configure within the
workspace ( custom objects fields etc )
## What's done
On both new workspace and seeded workspace creation:
- Creating a custom workspace app
- Creating a twenty standard app
- Refactored the seed core schema and workspace creation to be run
within a transaction in order to handle circular dependency foreignkey
requirements ( which is deferred for app toward workspace )
- Updated workspace entity to have a custom workspace relation (
nullable for the moment until we implem an upgrade command to handle
retro comp )
- Integration testing on user, workspace creation deletion and expected
default apps creation
- ~~Soft deleted user on `deleteUser`~~ Done by marie and rebased on it
## What's next
- Update seeder to propagate the `twenty-standard` workspace
`applicationId` to every standard synchronized entities ( cheap and fast
iteration through the about to be deprecated sync-metadata as an easy
way to synchronize standards metadata entities ).
- Update seeder to propagate the `custom-workspace-application`
workspace `applicationId` to anything custom ( `pets` and `rockets` )
- Prepend `custom-workspace-application` `applicationId` to every
metadata API operations ( create a specific cache etc )
- Upgrade command on all existing workspace to create a custom app and
associate its applicationId to any existing custom entities
- Make `universalIdentifier` and `applicationId` required for any
syncable entity
