fix(viewer): always show login button, never auto-redirect to IdP

Earlier behaviour: with a single OIDC provider configured, LoginPage useEffect-redirected to the IdP automatically, on the rationale "why make the user click an extra button when there's only one option." That's debugging-hostile in three ways: - The user can't see what app they're signing into or pause to read. - A transient IdP error (consent prompt closed, MFA timeout, network flap) ping-pongs them straight back to the IdP rather than letting them back out. - The flicker hides the brand and makes "did anything happen?" ambiguous. Always render the provider button instead. One extra click; much better failure visibility and clearer agency. Caught while smoke- testing local Entra round-trip — the user couldn't read the IdP page because the SPA auto-bounced them. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
