Jeremie Fraeys ea15af1833 Fix multi-user authentication and clean up debug code 
- Fix YAML tags in auth config struct (json -> yaml)
- Update CLI configs to use pre-hashed API keys
- Remove double hashing in WebSocket client
- Fix port mapping (9102 -> 9103) in CLI commands
- Update permission keys to use jobs:read, jobs:create, etc.
- Clean up all debug logging from CLI and server
- All user roles now authenticate correctly:
  * Admin: Can queue jobs and see all jobs
  * Researcher: Can queue jobs and see own jobs
  * Analyst: Can see status (read-only access)

Multi-user authentication is now fully functional.
