The commit refactors the previous implementation of using cache functions across several modules. They are now explicitly defined as loaders to improve readability and maintain a consistent style. This prevents the cache function calls from getting too nested and difficult to understand, especially in asynchronous cases. Additionally, the user session related hooks are deleted which were not used anymore.
The CSS classes in the billing pages of both the account and user sections have been modified. The 'mx-auto' class, which previously applied automatic horizontal margins to the elements, has been removed to adjust the layout.
