Add installers and CT templates for four apps

Add container templates (ct/) and install scripts (install/) plus metadata JSON entries for BunkerM, Colanode, Edit-Mind, and ExcaliDash. Each app includes an LXC template script with update routines, a corresponding installer that provisions dependencies, builds the app, configures services (systemd/nginx/supervisor), and example default environment/config. JSON metadata files register interface ports, recommended resources, documentation/website links, and notes for each app.
