Samir Boulahtit a8fae0fbc7 feat: implement metrics provider pattern for modular dashboard statistics
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
