Reworked service configuration to allow individual services to be conditionally excluded from the main index, increasing the flexibility of the display. Configuration files have been restructured and moved into appropriate subdirectories to improve project organization.
- Added `exclude_from_index` flags to all services within `services.json` to facilitate granular control over their visibility on the index page.
- Modified the `index.html` template to respect the new `exclude_from_index` setting, thus excluding specified services from being listed on the index page.
- Migrated `Caddyfile` and `privatecoffee.ini` to `contrib` directory for better separation of project contributions and core configuration files.
This update enhances the site's privacy features and enables easier navigation by allowing selective service display.
