refactor: add rate limiting to agent coordinator routers

- Added Request parameter to all endpoint functions in agents.py, ai.py, alerts.py, auth.py, and consensus.py
- Added @rate_limit decorator to all endpoints with appropriate limits:
  - Write operations (POST/PUT/DELETE): 50 requests per 60 seconds
  - Read operations (GET): 200 requests per 60 seconds
  - High-frequency operations (heartbeat, token refresh): 100 requests per 60 seconds
- Renamed conflicting request parameters (request -> request_http, request_status)
