Refactor rules acknowledgment logic and update role assignment behavior

- Removed the `on_presentation_message` function to streamline role assignment processes.
- Updated the `assign_rules_arrival_on_join` function to clarify its purpose, focusing solely on assigning the arrival role upon member join.
- Adjusted success message generation for role validation to enhance clarity and user experience.
- Modified configuration settings and web templates to reflect the updated role assignment behavior, ensuring accurate user guidance.
