feat(auth): add a generic OIDC login provider - #496
Conversation
Lets a self-hosted installation sign in against any standards-compliant OIDC provider, alongside the existing Google and GitHub options. - packages/auth: build an OIDC client from OIDC_* environment variables. Leaving them unset is fine; setting only some of them throws at boot rather than failing at the first login attempt. - packages/auth: report which providers are actually configured, so the dashboard only renders buttons that will work. - apps/api: handle the /oauth/oidc/callback leg, map claims to a user, and reject an unverified email however the provider spells that claim. - packages/trpc: accept 'oidc' in signInOAuth and expose an authProviders query. - apps/start: show the provider button on the login and onboarding pages, and hide the whole OAuth section when nothing is configured. - AUTH_AUTO_REDIRECT sends /login straight to the provider when exactly one provider is configured, and logs a warning at boot when it cannot apply. /login?noredirect=1 always renders the normal page, which is where logging out and deleting an account now land. - docs: environment variable reference for all of the above.

When
inviteIdis valid, the loader startsorganization.getInviteonly afterauthProviderscompletes. These prefetches have no data dependency, so this can keeppendingComponentvisible for both request durations instead of the slower request duration.♻️ Proposed refactor

- Around line 28-47: Add COOKIE_OPTIONS to the `@openpanel/auth` mock factory so
the OAuth callback can complete clearCookie and session setup without throwing.
In the success-path tests, also assert userCreate and setSessionTokenCookieMock
were called, alongside the existing callback assertions.
