Add protocol-based widget system following the MetricsProvider pattern:
- Create DashboardWidgetProviderProtocol in contracts/widgets.py
- Add WidgetAggregatorService in core to discover and aggregate widgets
- Implement MarketplaceWidgetProvider for recent_imports widget
- Implement TenancyWidgetProvider for recent_vendors widget
- Update admin dashboard to use widget_aggregator
- Add widget_provider field to ModuleDefinition
Architecture documentation:
- Add widget-provider-pattern.md with implementation guide
- Add cross-module-import-rules.md enforcing core/optional separation
- Update module-system.md with widget_provider and import rules
This enables modules to provide rich dashboard widgets without core modules
importing from optional modules, maintaining true module independence.

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

Add new validation rules MOD-020 to MOD-023 for module definition
completeness and standardize permissions across all modules.
Changes:
- Add MOD-020: Module definitions must have required attributes
- Add MOD-021: Modules with menus should have features
- Add MOD-022: Feature modules should have permissions
- Add MOD-023: Modules with routers should use get_*_with_routers pattern
Module permissions added:
- analytics: view, export, manage_dashboards
- billing: view_tiers, manage_tiers, view_subscriptions, manage_subscriptions, view_invoices
- cart: view, manage
- checkout: view_settings, manage_settings
- cms: view_pages, manage_pages, view_media, manage_media, manage_themes
- loyalty: view_programs, manage_programs, view_rewards, manage_rewards
- marketplace: view_integration, manage_integration, sync_products
- messaging: view_messages, send_messages, manage_templates
- payments: view_gateways, manage_gateways, view_transactions
Module improvements:
- Complete cart module with features and permissions
- Complete checkout module with features and permissions
- Add features to catalog module
- Add version to cms module
- Fix loyalty platform_router attachment
- Add path definitions to payments module
- Remove empty scheduled_tasks from dev_tools module
Documentation:
- Update module-system.md with new validation rules
- Update architecture-rules.md with MOD-020 to MOD-023
Tests:
- Add unit tests for module definition completeness
- Add tests for permission structure validation

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)

Extract three additional modules following the billing module pattern:
Inventory Module (app/modules/inventory/):
- Stock management and tracking
- Inventory locations
- Low stock alerts
- Admin and vendor routes with module access control
Orders Module (app/modules/orders/):
- Order management and fulfillment
- Order item exceptions
- Bulk operations and export
- Admin and vendor routes with module access control
Marketplace Module (app/modules/marketplace/):
- Letzshop integration
- Product sync
- Marketplace import
- Depends on inventory module
- Admin and vendor routes with module access control
Admin router updated:
- Uses module routers with require_module_access dependency
- Legacy router includes commented out
- Routes verified: 15 inventory, 16 orders, 42 marketplace
All 31 module tests passing.
