Add CT installers and metadata for six apps

Add container templates, install scripts and metadata for six applications: BirdNET-Go, ERPNext, Jitsi Meet, Storybook, Storyteller and Tube Archivist. New files include ct/* scripts (container templates and update handlers), install/* scripts (installation and systemd service setup, dependency installation and build steps) and json/* metadata entries (app catalog data, default resources, ports and notes). Each install script configures required dependencies, creates services, and prepares runtime configuration (e.g. DB, ElasticSearch, Node/Python environments, ffmpeg/Readium). This commit enables automated LXC provisioning and update flows for these apps.
