Remove unused MCP resources and update documentation

- Remove array_status, system_info, notifications_overview, and parity_status resources
- Keep only logs_stream resource (unraid://logs/stream) which is working properly
- Update README.md with current resource documentation and modern docker compose syntax
- Fix import path issues that were causing subscription errors
- Update environment configuration examples
- Clean up subscription manager to only include working log streaming
