Add automatic role assignment on member join for rules acknowledgment

- Introduced a new function `assign_rules_arrival_on_join` to assign the arrival role to members upon joining, based on configuration settings.
- Updated the `on_member_join` event to call the new function, enhancing the user experience by providing immediate role assignment.
- Modified configuration options in the web application to allow enabling or disabling this feature.
- Updated the configurations template to reflect the new role assignment behavior, ensuring clarity for users.
