**Title:** Implement ID-to-Name Mapping System
**Status:** done
**Dependencies:** 5 ✓
**Priority:** medium
**Description:** Create intelligent caching system for resolving company and resource IDs to human-readable names
**Details:**
Create mapping-service.ts with MappingService class. Implement in-memory cache with 30-minute TTL for company and resource name lookups. Add methods: getCompanyName(id), getResourceName(id), clearCache(), preloadCache(), getCacheStats(). Use Map for storage with automatic cleanup. Support bulk operations for efficient batch lookups with parallel processing.
**Test Strategy:**
Test cache hit/miss scenarios, TTL expiration, bulk lookup performance, graceful fallback for unknown IDs
