Use community-scripts defaults and tags

Standardize default credentials and template tags to the community-scripts identity. Updates:
- install/healthchecks-install.sh: change admin email to admin@community-scripts.com (secret generation unchanged).
- install/nodebb-install.sh: update interactive/default admin username, email, and password from helper-scripts to community-scripts.
- tools/addon/all-templates.sh and vm/opnsense-vm.sh: replace proxmox-helper-scripts tags with community-script for new templates/VMs.
This aligns branding across installers and VM/template creation.
