[BREAKING_CHANGE_NESTED_WORKSPACE]Refactor FlatEntity typing in aim of introducing UniversalFlatEntity (#16701)

# Introduction
Added a `WorkspaceRelated` and `AllNonWorkspaceRelatedEntity` to
simplify the `FlatEntityFrom` that now do not expect a string literal to
omit and itself builds the related many to one entities foreign key
aggregators

We now have the type grain over relation to syncable or just workspace
related entities

Added a migrations that sets the fk on missing entities

## Next
In upcoming PR we will be able to introduce such below type
```ts
import { type CastRecordTypeOrmDatePropertiesToString } from 'src/engine/metadata-modules/flat-entity/types/cast-record-typeorm-date-properties-to-string.type';
import { type ExtractEntityManyToOneEntityRelationProperties } from 'src/engine/metadata-modules/flat-entity/types/extract-entity-many-to-one-entity-relation-properties.type';
import { type ExtractEntityOneToManyEntityRelationProperties } from 'src/engine/metadata-modules/flat-entity/types/extract-entity-one-to-many-entity-relation-properties.type';
import { type ExtractEntityRelatedEntityProperties } from 'src/engine/metadata-modules/flat-entity/types/extract-entity-related-entity-properties.type';
import { type RemoveSuffix } from 'src/engine/workspace-manager/workspace-migration-v2/workspace-migration-builder-v2/types/remove-suffix.type';
import { type SyncableEntity } from 'src/engine/workspace-manager/workspace-sync/types/syncable-entity.interface';

export type UniversalFlatEntityFrom<TEntity extends SyncableEntity> = Omit<
  TEntity,
  | `${ExtractEntityManyToOneEntityRelationProperties<TEntity> & string}Id`
  | ExtractEntityRelatedEntityProperties<TEntity>
  | 'application'
  | 'workspaceId'
  | 'applicationId'
  | keyof CastRecordTypeOrmDatePropertiesToString<TEntity>
> &
  CastRecordTypeOrmDatePropertiesToString<TEntity> & {
    [P in ExtractEntityManyToOneEntityRelationProperties<TEntity> &
      string as `${RemoveSuffix<P, 's'>}UniversalIdentifier`]: string;
  } & {
    [P in ExtractEntityOneToManyEntityRelationProperties<
      TEntity,
      SyncableEntity
    > &
      string as `${RemoveSuffix<P, 's'>}UniversalIdentifiers`]: string[];
  };

```
