fix(auth): route /api/auth/sso-exchange through the v1 rewrite shim

Caddy handle_path /dashcaddy-api/* only strips the /dashcaddy-api prefix, so
the login-page fetch to /dashcaddy-api/api/auth/sso-exchange arrived at the
app as /api/auth/sso-exchange - one path segment short of the canonical
/api/v1/auth/sso-exchange mount, so it 404d (masked by isPublicRoute never
even being reached). Add it to the same narrow gate/app-token rewrite case.
Caught by an end-to-end curl replay of the actual handoff flow before
asking for another live retest.
