chore(labels): park the label designer and printing on feature/labels

The feature needs more rounds than the next release can wait for, so main goes
back to before it: the packages, bindings, migration, UI and i18n all move to
the feature/labels branch, which holds every commit. The 0.26.23 block keeps
only the Station column.

The 0031 migration may already have run on a machine that launched a dev build;
the two label tables it created are inert and the recorded migration row is
harmless — the runner only applies filenames it has, so re-adding the migration
when the branch merges will skip cleanly there and apply everywhere else.
