### What problem does this PR solve?
This PR fixes SSO/OIDC login persistence after the Vite migration
#12568. Because wrappers are ignored by React Router, the OAuth callback
never stored the auth token in localStorage, causing auth to only work
while ?auth= stayed in the URL. We move that logic into a route loader
and remove the Bearer prefix for the signed token so the backend accepts
it.
