feat: rules engine — json-rules-engine integration with worklist scoring

- Self-contained NestJS module: types, storage (Redis+JSON), fact providers, action handlers - PriorityConfig CRUD (slider values for task weights, campaign weights, source weights) - Score action handler with SLA multiplier + campaign multiplier formula - Worklist consumer: scores and ranks items before returning - Hospital starter template (7 rules) - REST API: /api/rules/* (CRUD, priority-config, evaluate, templates) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
