Add Store/Region Name to Weekly Report Email Subject

When managing multiple storefronts or regional stores, it is currently difficult to identify which store the weekly STOQ report email belongs to, as the email subject line remains generic (STOQ | Your weekly preorders & back in stock report)

Example storefronts:

• Australia

• Global

• UK

Currently, the report emails do not include any store, region, or storefront identifier, which can create confusion when reviewing reports across multiple stores.

Requested improvement:
Include the store name, region, or storefront identifier in the email subject line or heading so the correct storefront can be identified immediately.
