Merge 81a59edf03 into 640e5616e9

When /api/auth/app-config fails (ZT redirect, network blip) the login page
now shows a warning banner with a Refresh button instead of silently omitting
the SSO sign-in button. The SW also now applies authRedirectPlugin to this
endpoint so ZT opaque redirects are converted to 401 AUTH_REQUIRED rather
than causing a JSON parse failure that went undetected.

Translations added for all 15 supported languages.
