Add rel="noreferrer" to external links in contact page

[Copilot]

External links with target="_blank" in the contact page were using only rel="noopener" instead of rel="noopener noreferrer", inconsistent with the pattern used throughout the rest of the application.

Changes:

• Updated 5 external links (Instagram, LinkedIn, GitHub, Discord, shop location) to use rel="noopener noreferrer"
• Matches pattern used in footer, donate page, and sponsors page

 <a
   target="_blank"
-  rel="noopener"
+  rel="noopener noreferrer"
   href="https://www.instagram.com/wazzu_racing"
 >

This prevents referrer leaking on external navigation.
