refactor(twenty-orm): migrate 23 grandfathered entities to WorkspaceScopedRepository (#20987)

## Summary

Follow-up to #20953. Migrates 23 of the 30 entities that were left in
`WORKSPACE_SCOPED_EXEMPTIONS` last time, so the lint rule's
workspaceId-enforcement default now covers most of the core/metadata
schema.

### Migrated (23 entities, 88 files, 22 commits)

| Family | Entities |
|---|---|
| Trivial caches | `NavigationMenuItem`, `Skill`, `DataSource`,
`Webhook`, `CommandMenuItem`, `IndexMetadata` |
| Views | `View`, `ViewField`, `ViewFieldGroup`, `ViewFilter`,
`ViewFilterGroup`, `ViewGroup`, `ViewSort` |
| Layouts | `PageLayout`, `PageLayoutTab`, `PageLayoutWidget` |
| Roles & permissions | `Role`, `RoleTarget`, `PermissionFlag`,
`ObjectPermission`, `FieldPermission`, `RowLevelPermissionPredicate`,
`RowLevelPermissionPredicateGroup` |

For each entity: swap `@InjectRepository(X)` →
`@InjectWorkspaceScopedRepository(X)` (and the field type →
`WorkspaceScopedRepository<X>`); rewrite every call site to pass
`workspaceId` as the first arg (stripped from `where`/criteria — the
wrapper throws if you include it now); register
`provideWorkspaceScopedRepository(X)` in every owning NestJS module;
update affected spec providers to
`getWorkspaceScopedRepositoryToken(X)`.

### Rule update

- `ApplicationRegistrationVariableEntity` was misclassified — moved to
`STRUCTURAL_EXEMPTIONS` (no `workspaceId` column; it's keyed on
`applicationRegistrationId` at the instance level).
- 22 of the 23 migrated entities removed from
`WORKSPACE_SCOPED_EXEMPTIONS` entirely (zero remaining raw
`@InjectRepository` sites).
- `RoleTargetEntity` also removed; one call site in
`user-workspace.service.ts` keeps a raw injection with an
`eslint-disable` + reason because `softRemove(...)` is not on the
wrapper API yet (the migration would require threading `workspaceId`
through `deleteUserWorkspace`'s three callers).

### Still exempted (7 entities, follow-up PRs)

| Entity | Why deferred |
|---|---|
| `ApplicationEntity` | ~50 sites with several cross-workspace lookups
by id (auth, OAuth, file-storage, cleanup) |
| `CalendarChannelEntity` / `MessageChannelEntity` | Use
`.increment(...)` (not on wrapper) and
`repository.manager.transaction(...)` — wrapper needs to grow
`.increment` + the transaction sites need `withManager` or dual-inject |
| `FieldMetadataEntity` / `ObjectMetadataEntity` | The metadata services
`extends TypeOrmQueryService<X>` and `super(rawRepo)` — requires
dual-inject or reworking the inheritance |
| `KeyValuePairEntity` | Allows `workspaceId: IsNull()` for
instance-level config; wrapper rejects null |
| `UpgradeMigrationEntity` | Same — instance-level + cross-workspace
ledger |

## Test plan

- [x] `npx nx typecheck twenty-server` — clean
- [x] `npx nx lint twenty-server` — clean (0/0)
- [x] All 10 affected unit specs pass (115 tests) — api-key, agent-role,
permissions, workspace-roles-permissions-cache, view-filter-group,
workflow-version-step-operations, two-factor-authentication (service +
resolver), user-workspace, file
- [ ] Server integration tests in CI
