Greptile Summary

Pro plan users hitting the 1-policy backup limit were previously navigated to the change-plan page, which only shows Free/Pro options and left them stuck. This PR replaces both internal navigation handlers with external links to https://appwrite.io/contact-us/enterprise and updates the button text to "Upgrade to Enterprise".

• Both occurrences of the upgrade prompt (isFromBackupsTab branch and the InputSwitch description) now open the enterprise contact page in a new tab instead of routing within the app.
• Unused imports (goto, getChangePlanUrl, showCreatePolicy) are cleaned up correctly.

Confidence Score: 5/5

Safe to merge — minimal, well-scoped change that only affects the upgrade CTA links shown to Pro plan users in the backup policy UI.

The change is purely a UI link fix: two click handlers that navigated internally are replaced with external anchor targets, and three imports that became dead code are removed. No logic, state, or data flow is altered beyond what the PR intends.

No files require special attention.
