Michelle	4aea069295	fix: resolve server bugs and unify app-name handling Build & Push Docker Image / build (push) Successful in 4m6s Details Bug fixes: - bbb.js: replace undefined t('defaultWelcome') call that threw a ReferenceError when a room had an empty welcome message, breaking meeting creation. Default welcome and the guest-invite hint are now localised via the i18n system (new "bbb" namespace in de/en). - auth.js: app name was read from the never-written 'branding' settings key, so custom names never appeared in verification emails or the TOTP issuer. Now resolved through a shared getAppName() helper. - auth.js: lowercase the email in the registration duplicate check so case-variant duplicates return a clean 409 instead of a 500 (UNIQUE violation). - federation.js: select the user's "language" column so federation invite emails respect the recipient's language instead of always defaulting to English. - calendar.js: a set reminder could not be cleared. COALESCE treated an explicit reminder_minutes: null as "keep existing"; use a direct assignment that distinguishes "omitted" (keep) from "null" (clear). - index.js / analytics.js: exclude the BBB learning-analytics callback from the global 100kb body limit and give it its own 5mb limit, since analytics payloads for large meetings can be several MB. Cleanup: - Add server/config/appName.js as the single source of truth for the app name (admin setting -> APP_NAME env -> 'Redlight') and use it in auth, admin, rooms, calendar and federation, replacing the previous mix of wrong DB key, direct app_name reads and bare process.env reads. - Localise the BBB default welcome message in the room owner's language. - Remove two unused safeAppName variables in mailer.js.	2026-06-02 09:19:21 +02:00
