Fix logout/login redirects in subpath deployments (#46715)

Fixes #46639

Hard-coded "/" and "/login" strings bypassed the URL prefix when Fleet
is deployed behind a reverse proxy at a subpath. Replaced with
PATHS.ROOT / PATHS.LOGIN, which embed URL_PREFIX, so redirects now land
at the correct subpath.
