This commit introduces a protocol-based metrics architecture that allows
each module to provide its own statistics for dashboards without creating
cross-module dependencies.
Key changes:
- Add MetricsProviderProtocol and MetricValue dataclass in contracts module
- Add StatsAggregatorService in core module that discovers and aggregates
metrics from all enabled modules
- Implement metrics providers for all modules:
- tenancy: vendor/user counts, team members, domains
- customers: customer counts
- cms: pages, media files
- catalog: products
- inventory: stock levels
- orders: order counts, revenue
- marketplace: import jobs, staging products
- Update dashboard routes to use StatsAggregator instead of direct imports
- Fix VendorPlatform junction table usage (Vendor.platform_id doesn't exist)
- Add comprehensive documentation for the pattern
This architecture ensures:
- Dashboards always work (aggregator in core)
- Each module owns its metrics (no cross-module coupling)
- Optional modules are truly optional (can be removed without breaking app)
- Multi-platform vendors are properly supported via VendorPlatform table

This commit completes the migration to a fully module-driven architecture:
## Models Migration
- Moved all domain models from models/database/ to their respective modules:
- tenancy: User, Admin, Vendor, Company, Platform, VendorDomain, etc.
- cms: MediaFile, VendorTheme
- messaging: Email, VendorEmailSettings, VendorEmailTemplate
- core: AdminMenuConfig
- models/database/ now only contains Base and TimestampMixin (infrastructure)
## Schemas Migration
- Moved all domain schemas from models/schema/ to their respective modules:
- tenancy: company, vendor, admin, team, vendor_domain
- cms: media, image, vendor_theme
- messaging: email
- models/schema/ now only contains base.py and auth.py (infrastructure)
## Routes Migration
- Moved admin routes from app/api/v1/admin/ to modules:
- menu_config.py -> core module
- modules.py -> tenancy module
- module_config.py -> tenancy module
- app/api/v1/admin/ now only aggregates auto-discovered module routes
## Menu System
- Implemented module-driven menu system with MenuDiscoveryService
- Extended FrontendType enum: PLATFORM, ADMIN, VENDOR, STOREFRONT
- Added MenuItemDefinition and MenuSectionDefinition dataclasses
- Each module now defines its own menu items in definition.py
- MenuService integrates with MenuDiscoveryService for template rendering
## Documentation
- Updated docs/architecture/models-structure.md
- Updated docs/architecture/menu-management.md
- Updated architecture validation rules for new exceptions
## Architecture Validation
- Updated MOD-019 rule to allow base.py in models/schema/
- Created core module exceptions.py and schemas/ directory
- All validation errors resolved (only warnings remain)
