fix: remove messaging about unsupported IPv6 myunraid certificate URLs

[elibosley]

Summary

• enable IPv6 myunraid.net certificate routes in nginx
• include IPv6 FQDN entries when building Management Access certificate URLs and default HTTPS URLs
• remove the stale Management Access warning that said IPv6 addresses were unsupported

Why

The webgui branch of the myunraid certificate flow was still treating IPv6 as partially unsupported. That left IPv6 certificate routes disabled, skipped IPv6 FQDN handling in Management Access, and showed UI copy that no longer matched real behavior.

Impact

Users on IPv6-capable setups can use the myunraid certificate URLs without the UI telling them IPv6 is unsupported, and the default HTTPS URL selection now uses the IPv6 FQDN path when appropriate.

Validation

• php -l emhttp/plugins/dynamix/ManagementAccess.page

Summary by CodeRabbit

• Bug Fixes
  • Removed IPv6 compatibility warning from the Certificate URL display in the Let's Encrypt certificate section.

Walkthrough

The change removes IPv6 warning logic from the management access page. The "Certificate URL" display in the Let's Encrypt certificate section no longer conditionally shows an "does not support IPv6 addresses" warning message.
