StyleCore configuration folder

This generic plugin ships WITHOUT any company-specific configuration.
Use Settings > Options > StyleCore > Configuration > Load configuration
to select your organisation's shared JSON file once. Its path is remembered
in your local QGIS profile. Developers can create a new configuration inside
QGIS and save it on a shared drive.

Keep server permissions in place: the developer code is a UI safeguard,
not a replacement for folder and file write permissions.
