Add container templates and installers for apps

Add new ProxmoxVED container templates (ct/*.sh), install scripts (install/*.sh) and metadata (json/*.json) for multiple applications: Akaunting, Blinko, Certimate, Dagu, Gogs, InvoiceShelf, Matomo, Papermark, RSS-Bridge, SolidTime and WhoDB. Each ct script includes update logic and deployment helpers; install scripts handle dependency installation, service creation (systemd), DB setup, and Caddy/PHP/Node/Postgres configuration where applicable. JSON entries provide UI metadata, resource defaults and access ports for each app.
