refactor: add rate limiting to agent performance, cache management, confidential, dynamic pricing, and edge GPU routers

- Added Request parameter to all endpoint functions in agent_performance.py, cache_management.py, confidential.py, dynamic_pricing.py, and edge_gpu.py
- Added @rate_limit decorator to all endpoints with appropriate limits:
  - Write operations (POST): 20 requests per 60 seconds
  - Read operations (GET): 200 requests per 60 seconds
  - High-frequency reads (health checks, available strategies): 500-1000 requests per 60
