Make sure directors and managers see correct store data

Fixes an issue where directors and managers might see data from multiple stores incorrectly. Ensures roles with limited store access only view their designated information and prompts explicit store selection when no store is chosen. Updates the UI to correctly display store selectors based on user roles. Also adds cache invalidation for user data upon authentication updates and refines API filtering for orders and deliveries to respect user roles and store selections.
