Oidc password authentication on uninitialized Oidc fix

[SangJunBak]

Before we were getting throws on password login when Oidc was never initialized. This allows us to not have to check if the oidcManager is available everytime we want Oidc auth details.

Motivation

Bug found during product review when logging in as mz_system before Oidc was configured

Verification

Run locally against Oidc instance and login as mz_system. Before you would crash because we were trying to access properties in useAuth that didn't exist. Now it doesn't crash

[SangJunBak]

I feel like a follow up to this is an e2e test framework that:

1. Runs the Console locally
2. Stands up a Materialize instance with the right config using mzcompose.ts
3. Uses playwright to just login as mz_system using password auth

Then perhaps using frontegg-mock, we could do something similar for oidc.

LGTM

this is cool! Didn't know retryOnMount was a thing

Suggested change

	useEffect(() => {
	const oidcError = auth.error?.message? ?? null;
	const displayError =
	error ||
	(oidcAuthErrorMessage &&
	`${oidcAuthErrorMessage}. It looks like there may be an issue with the sign-in configuration. Please review your OIDC settings or check the console logs for more information.`) ||
	null;
	return (
	<VStack spacing="2" alignItems="center">
	{displayError&& <Alert variant="error" minWidth="100%" message={error} />}

I imagine this flow should work

1. . App mounts → auth.error = null → oidcError = undefined → displayError = null → no Alert.
2. react-oidc-context populates auth.error → AuthProvider re-renders consumers.
3. SsoLoginLink re-renders → oidcError is recomputed from auth.error.message → displayError is the friendly message → Alert appears.
4. User clicks SSO → handleSsoLogin runs → if signinRedirect() rejects, setError(...) runs → next render, error (local) wins via || short-circuit → Alert swaps to that message.
5. Issuer is fixed and the user reloads → auth.error clears → displayError = null → Alert disappears.

Makes sense to me!
