Describe the bug
Currently, when content is published/posted in OJS/OMP/OPS, editors are restricted from making further changes:

In practice, however, editors want the ability to tweak/edit metadata in published content. This has led to anti-patterns like unpublish/edit/republish cycles.

In OMP, there is an additional problem, where certain data on Publication Formats can't be accessed/reviewed because the edit links disappear once the content is published.

Accepting that editors are going to want to tweak metadata after publication, we should keep the warning message present, but stop restricting edits. We should trust the editors to understand the implications of making edits, but not try to prevent it.
