Created generic tooling for entity circular dep checking, will be useful
for permissions validation too @Weiko


## Migrate `viewFilterGroup` entity to v2 flat architecture

### Summary
Migrates the `viewFilterGroup` entity from v1 to the v2 flat entity
architecture, following the established patterns for other v2 entities
like `viewFilter`, `view`, and `viewField`.

### Changes

**Types & Constants**
- Added `FlatViewFilterGroup` and `FlatViewFilterGroupMaps` types
- Added editable properties constant for `viewFilterGroup`
- Registered `viewFilterGroup` in `ALL_METADATA_NAME`,
`ALL_METADATA_RELATION_PROPERTIES`,
`ALL_METADATA_MANY_TO_ONE_RELATIONS`, and related constants

**Cache Service**
- Created `WorkspaceFlatViewFilterGroupMapCacheService` with proper
relation loading for `viewFilters` and `childViewFilterGroups`
- Updated `WorkspaceFlatViewMapCacheService` to load `viewFilterGroups`
relation

**Builder & Validator**
- Created `WorkspaceMigrationV2ViewFilterGroupActionsBuilderService`
- Created `FlatViewFilterGroupValidatorService` with creation, update,
and deletion validation
- Integrated validation into the orchestrator service (runs before
`viewFilter` validation)

**Action Handlers**
- Created create, update, and delete action handlers for
`viewFilterGroup`

**Service Migration**
- Rewrote `ViewFilterGroupService` to use v2 migration pattern with
`WorkspaceMigrationValidateBuildAndRunService`
- Created utility functions for transforming DTOs to flat entities

**Database Migration**
- Added migration to make `parentViewFilterGroupId` foreign key
deferrable (handles self-referential parent/child insertions)

**ViewFilter Integration**
- Added `viewFilterGroupId` validation in
`FlatViewFilterValidatorService`
- Updated `viewFilter` many-to-one relations to include
`viewFilterGroup`

**Tests**
- Added integration tests for successful creation, update, deletion, and
destruction
- Added failing test cases for non-existent entities and invalid
references
- Added failing test for `viewFilter` creation with non-existent
`viewFilterGroupId`

### Breaking Changes
None - existing API contracts are preserved.
