Add Stoatchat and xyOps container/install scripts

Introduce new container templates, installers, and metadata for Stoatchat and xyOps. Adds ct scripts (ct/stoatchat.sh, ct/xyops.sh), full install scripts (install/stoatchat-install.sh, install/xyops-install.sh) that provision dependencies, build components, and create systemd services, plus app metadata JSON (json/stoatchat.json, json/xyops.json). Stoatchat installer handles Rust backend build, SolidJS frontend build, MinIO, RabbitMQ, MongoDB, nginx reverse proxy and multiple backend services (exposes on port 80). xyOps installer builds the Node app, sets up the xySat satellite, service unit, and uses port 5522 for the web UI. Default resource recommendations and notes are included in the JSON metadata.
