Profile page navigation error blocks profile acceptance testing

[flyblackbox]

Summary

A profile-page error currently prevents completion of acceptance testing for the About/bio editing work delivered in #434 and tracked in #362.

Current evidence

@niamao reported that an error occurs when navigating to the profile page. The exact route, account state, visible error, and underlying console/network/GraphQL failure still need to be captured.

Reproduction details needed

• Record the affected profile route.
• Record whether the viewer is authenticated, logged out, or viewing another user.
• Provide reliable reproduction steps.
• Capture the visible error state.
• Capture relevant console, network, and GraphQL errors.
• Confirm whether the updateUser bio mutation succeeds before navigation or rendering fails.

Resolution tasks

• Identify the failing component, query, or route transition.
• Add regression coverage for the reproduced failure.
• Restore successful profile-page navigation and rendering.
• Re-test the About field save-and-persist flow from RC1-011 Allow users to update About section from Edit Profile #362.

Acceptance criteria

• The affected profile route loads without the reported error.
• Existing profile content renders for the relevant account state.
• About/bio changes can be saved, followed by a successful profile reload.
• A regression test covers the underlying failure.
