Improve clarity of ToU/Privacy Policy modal wording

[thomaspiller]

Describe the issue
The text displayed in the modal used to accept the ToU and Privacy Policy could be improved.
Currently, it is not entirely clear to users that the modal content is only a summary of the key points of the ToU/Privacy Policy.

Proposed improvement

• Explicitly indicate that the modal contains a summary of the key points.
• Clarify that the full ToU and Privacy Policy are available via the provided links.

Expected behavior
Users should clearly understand that the modal text is a summary and that the authoritative, complete versions are accessible through the links.
