Fix member portal: remove CV Updates, fix logo links, clean auth flow (v1.10.1)

- Remove "CV Updates" from member sidebar (admin-only function)
- Top bar ai.med logo is non-clickable (stays in portal)
- Only sidebar ai.med logo links back to public site
- Auth error redirects to /admin login (not activation page)
- All /member/* and /admin/* routes properly hide public chrome
