SUPP-121: Repair broken changelog redirects in Data Clean-Up and EU Residency docs

[Copilot]

Two docs pages linked to changelog permalink paths that now 404 in Mintlify (/changelogs/<date-slug>). This updates those references to the canonical changelog page anchors so users land on the intended entries.

• What changed

  • Data Clean-Up (Other resources)
    • Updated the Event Approval link from a dead dated changelog route to the live changelog anchor.
  • EU Residency (Storing Your Data in the European Union)
    • Updated the deprecation changelog reference from a dead dated changelog route to the live changelog anchor.

• Link target updates

  - [Event Approval](/changelogs/2023-06-01-event-approval)
  + [Event Approval](/changelogs#vet-new-events-and-ensure-data-trust-with-event-approval)
  
  - See [changelog here](/changelogs/2026-02-20-eu-forwarding-deprecation).
  + See [changelog here](/changelogs#deprecation-notice-legacy-us-to-eu-data-forwarding-ends-july-2026-for-eu-projects).

Branch naming

This task relates to issue SUPP-121 — preserve that identifier somewhere in the branch name and pull request title for traceability. Do not treat the identifier as a verbatim slug or prepend it with a hyphen by default; instead, adapt the full branch name to comply with the repository's branch-naming pattern, adding any required prefix or restructuring the shape as needed.

Include a link to the original issue in the pull request description: https://linear.app/mixpanel/issue/SUPP-121/bug-changelog-link-redirects-to-404-page

Confidence Score: 5/5

Safe to merge — two targeted link fixes in documentation files with no logic changes.

Both updated anchors correspond exactly to ## headings in their respective snippet files, which are imported and rendered on the /changelogs page. No other files are touched.

No files require special attention.

Important Files Changed

Filename	Overview
docs/data-governance/data-clean-up.mdx	Updated Event Approval changelog link from a 404-returning page URL to an anchor on the consolidated /changelogs page; anchor matches the rendered heading.
docs/privacy/eu-residency.mdx	Updated EU forwarding deprecation changelog link from a 404-returning page URL to an anchor on the consolidated /changelogs page; anchor matches the rendered heading.
