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 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
