This update corrects how the Amazon and eBay sales connectors declare their required marketplace components. It helps keep module installation and maintenance cleaner without changing day-to-day marketplace workflows.

Marketplaces rely on `stock` and `delivery`, and module bridge `stock_delivery` is sufficient, no need to explicitly add `stock`.

The rental website settings now show the Unavailability days option correctly. This prevents confusion when configuring rental availability and helps administrators verify their settings more easily.

This commit simply corrects how the Unavailability days setting is displayed
