Change Foldergram installation to store media and config under /opt/foldergram_media (create media dir, write env file there, update systemd EnvironmentFile). Update ct/foldergram.sh to remove temporary backup/restore during updates. Update json/foldergram.json config_path and add an info note about where to place media. Add tools/pve/ct-batch-create.sh — a new Proxmox CT batch-creator script (interactive/unattended modes, caching, storage selection) to download and deploy multiple community-scripts CTs.
Migrated all 80 app JSON files to place config_path inside each
install_methods object instead of at the root level. This allows
different install methods (e.g. Debian vs Alpine) to have distinct
config paths.
Also updated AGENTS.md JSON structure example to reflect the change.
