Resolves the billing (core) → monitoring (optional) architecture violation
by moving CapacityForecastService to the monitoring module where it belongs.
- Create BillingMetricsProvider to expose subscription counts via stats_aggregator
- Move CapacitySnapshot model from billing to monitoring
- Replace direct MerchantSubscription queries with stats_aggregator calls
- Fix middleware test mocks to cover StoreDomain/MerchantDomain fallback chains

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)
