fix(tests): align auth tests with NotAuthenticatedError and 302 redirect

The auth dependency raises NotAuthenticatedError (not HTTPException),
and the exception handler returns a 302 redirect. Updated the unit test
to expect NotAuthenticatedError, and all route auth tests to accept 302
alongside 401/303.
