This commit dates the transition from a global user session to individual account handling based on user ID. The transition was made across several components, notably the account settings, icons, and selector. This change improves performance by reducing unnecessary requests and ensures more accurate data handling. The commit also includes some cleanups and minor fixes spread across different components.
The billing services have been refactored to use the new AccountsApi and TeamAccountsApi. All methods that were previously defined in each billing service, including getting customer ID, getting permissions, etc., have been transferred to these APIs. This change improves the modularity and organization of the code.
