## 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
While removing the v1 https://github.com/twentyhq/twenty/pull/15823 I've
encountered the method `objectMetadataService.deleteObjectsMetadata`
that I didn't wanted to migrate as it is and if it's not challenging its
existence legitimacy.
## Motivations
In a nutshell on a workspace deletion object metadata and field metadata
cascading deletion is correclty handled
But that's not the case for all of a workspaces entities ( roles,
workspaceMigrations ) I suspect that we did not defined the foreignKey
explicitly through `typeorm`
## Battle testing v2
I still decided to give a try to a complex operation in the v2 such as a
workspace all object metadata deletion.
Spoiler it failed due to object being interdependent between them and
not being topologically sorted ( morph relation can introduce circular
dep anw ).
Note: Even after removing the delete field on delete object aggregator
we end up with an equivalent circular dep error which an object and its
field metadata identifier connection.
## Elegant `DEFERRED` and `DEFERRABLE` foreign keys
The most safe, low level solution would be to make all field relations
deferrable and start the runner transaction as deferred. But this
requires a quite invasive migration of existing FK
## On cascade solution
I've opted for the quick fix, on object or field deletion spread
cacasde.
It's pretty safe as the builder priorly validates the deletion and and
its related entities integrity
Only for both field and object deletion action types in v2 runner
## Integration coverage
Added a test that will scan a new workspace database core schema tables
and expect now result after workspace deletion through its only user
deletion
In this PR
- closing https://github.com/twentyhq/core-team-issues/issues/313
- adding permission gates on workspace settings and security settings
- adding integration tests for each of the protected setting and
security
In this PR
1. Add integration tests for /metadata (master issue:
https://github.com/twentyhq/twenty/issues/8719)
2. Fix relation deletion: index on "from" object was not deleted,
impeding creation of a new relation between the same two objects A and B
after relation between A and B was deleted
