Wiki.js auto-provisions SSO users in processProfile without a timezone, so
the DB column default (America/New_York) applies. Since there is no Wiki.js
image build pipeline, patch server/models/users.js at container startup to set
timezone: 'Europe/Berlin' on new-user creation. Idempotent (grep guard) and
fail-open (node starts even if the anchor is gone after an upgrade).
