feat: implement ai status command with combined service status

Added handle_ai_status function that checks both Agent Coordinator (port 9001)
and Blockchain AI stats (port 8006), combining them into a comprehensive status
display. This fixes the Stage 5 certification test that was failing because
ai status required a job_id.

Changes:
- Added handle_ai_status function in cli/handlers/ai.py
- Updated AI parser to use handle_ai_status instead of handle_ai_job
- Registered handle_ai_status in unified_cli.py
- Fixed default coordinator URL from 8011 to 9001 (correct Agent Coordinator port)
- Added --coordinator-url argument to ai status parser

The command now runs without arguments and returns exit code 0, allowing
the certification test to pass.
