allow ui login w/o auth in dev

#3094

when frontend envName="DEV" and backend has google auth off, the login screen is skipped and you are "Dev User".

Requests will be sent with a specific fake "token" when you are Dev User to make sure the logs show that. It may not really matter, but there can also be the "System User" in there in the logs, so seemed like you might want to differentiate.

Non-DEV: initializeGoogleSignInButton called directly, no HTTP
DEV + auth off: two dispatches (actionSetGoogleCredential + actionLoginStart) with the fake credential, no Google button
DEV + auth on: falls back to Google button
DEV + auth off but no devUser in response: also falls back to Google button

Pull request overview

Adds a DEV-only “no-auth” login flow so local development can bypass the Google sign-in UI when the backend is configured with Google auth disabled, while still tagging requests with a distinct fake credential for clearer auditing/log attribution.

Changes:

• Frontend: in DEV, calls a new backend /login/check-auth endpoint to decide whether to auto-login as a dev user (dispatching a fake credential) vs. rendering the Google sign-in button.
• Backend: adds /api/login/check-auth, introduces fake-credential handling in authorization to attribute requests to either a dev user or system user when auth is off, and seeds a dev user.
• Updates test coverage for the new endpoint/flow and adjusts backend .env example defaults for local development.
