wger's image runs `manage.py migrate` only when DJANGO_PERFORM_MIGRATIONS=True (entrypoint.sh).
Without it, 2.6 -> 2.7 through the guarded Update on 9202 ended `done` and left 12 migrations
unapplied: the web login answered 500 (no such column: core_userprofile.time_zone). With the switch,
the same step on 9202 ran the migrations and the seeded weight entry read back. No image moves here;
no box reporting to the hub runs wger.
