fix: resolve MCP server startup and configuration issues

- Remove duplicate uvx commands from docker-compose.yml (blender, freecad, gimp)
- Update ghost-mcp to use default environment values for testing
- Update crush.json LSP commands with proper start arguments
- Add ffmpeg dependency to audiobook-mcp Dockerfile
- Create .env file with dummy values for all MCP servers
- Update STATUS.md for ghost-mcp working status

Note: gimp-mcp entrypoint fix excluded (vendor directory is gitignored)
