Slavi Pantaleev 0f687a69c5 matrix-synapse: simplify redundant SSO main-override regexes ...

MDAD keeps `/_synapse/client/*` out of the broad worker-routing model.
Those paths are mounted by current Synapse on client-serving workers, but MDAD's
worker route buckets only match `/_matrix/client/*`, so `/_synapse/client/*`
requests already fall through to the main-process default.

That made the `/_synapse/client/*` branches in the dedicated SSO override regex
redundant. Remove those branches and leave the explicit SSO override focused on
the real `/_matrix/client/.../login/sso/redirect` path family, which would
otherwise be caught by the broad `/login` client-reader routing.

This also removes duplicated ownership of `login/sso/redirect` from the generic
main-override regex so the dedicated SSO override is the single place that
models that path.
