fix: revert auth verification timeout to non-fatal warning

Auth request verification is a supplementary check that happens after
Authorino CR status is already confirmed ready. Timing out on the auth
verification shouldn't be fatal - it should continue with a warning,
similar to the gateway URL check.

This reverts the timeout behavior to match the original intentional
design: proceed with deployment even if auth verification times out.
