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 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

This module uses the StatsAggregator service from core to collect metrics from all

enabled modules. Each module provides its own metrics via the MetricsProvider protocol.
|
||||
|
||||
For backward compatibility, this also falls back to the analytics stats_service
|

for comprehensive statistics that haven't been migrated to the provider pattern yet.

- Dashboards always work (aggregator is in core)

- Each module owns its metrics (no cross-module coupling)

- Optional modules are truly optional (can be removed without breaking app)

- Easy to add new metrics (just implement MetricsProviderProtocol in your module)
