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)
