chore: add previously created MCP wrapper scripts

Add MCP wrapper scripts that were created during earlier troubleshooting
but were not committed yet. All wrappers follow same pattern:

- Container cleanup before starting new instance
- Explicit naming with -crush suffix
- Environment variable passing from host .env file
- Special cases handled (docker-mcp socket mount)

Scripts added:
- mcp-audiobook-wrapper.sh
- mcp-bitwarden-wrapper.sh
- mcp-blender-wrapper.sh
- mcp-cloudron-wrapper.sh
- mcp-docker-wrapper.sh (with Docker socket mount)
- mcp-drawio-wrapper.sh
- mcp-elasticsearch-wrapper.sh

All scripts are executable and tested.

mcp-drawio-wrapper.sh
