Fix: Architecture issues for CI/CD Quality Assurance

**Alembic Migration:**
- Named foreign key constraints (fk_topics_client_id, fk_guides_client_id, fk_snippets_client_id)
- Enables proper downgrade functionality

**Service Layer:**
- Updated ContentService.create_topic/create_guide/update_topic/update_guide
- Added current_client parameter for proper client isolation
- Forces client_id from authenticated context (security fix)

**MyPy Configuration:**
- Created mypy.ini with pgvector ignore (missing type stubs)
- Configured strict type checking with Pydantic plugin

**Test Fixes:**
- Updated test_create_topic_slug_collision with mock_client
- Fixed test_logging with proper mock structures for MyPy

**CI/CD:**
- Updated Postgres DB name from 'app' to 'app_test' in workflow
- Ensures env vars match service configuration

Tests: 30/30 ✅ | Coverage: 79%
