feat: Add dedicated dashboard methods to service clients

Created typed, domain-specific methods in service clients instead of
using generic .get() calls with paths. This improves type safety,
discoverability, and maintainability.

Service Client Changes:
- ProcurementServiceClient:
  * get_pending_purchase_orders() - POs awaiting approval
  * get_critical_alerts() - Critical severity alerts
  * get_alerts_summary() - Alert counts by severity

- ProductionServiceClient:
  * get_todays_batches() - Today's production timeline
  * get_production_batches_by_status() - Filter by status

- InventoryServiceClient:
  * get_stock_status() - Dashboard stock metrics
  * get_sustainability_widget() - Sustainability data

Dashboard API Changes:
- Updated all endpoints to use new dedicated methods
- Cleaner, more maintainable code
- Better error handling and logging
- Fixed inventory data type handling (list vs dict)

Note: Alert endpoints return 404 - alert_processor service needs
endpoints: /alerts/summary and /alerts (filtered by severity).
