[!NOTE] Tightens import-tokens modal UI by boldening the confirmation header and fixing the scam warning link using TextButton-wrapped anchor.

UI:

Increase header emphasis in import-tokens-modal-confirm.js by setting Text fontWeight to Medium.

Update scam warning link in import-tokens-modal.js to use TextButton (wrapping an <a>), improving rendering and external link handling to ZENDESK_URLS.TOKEN_SAFETY_PRACTICES.
