Add full views integration for the content dashboard

Problem/Motivation

Several users have mentioned wanting to filter the results dashboard by various things -- groups membership, pages they have authored or recently edited, node published status, etc.

Proposed resolution

Adjusting the data tables a bit should allow for mapping certain fields to Drupal's NID and TID tables, which would allow for creating Views relationships and showing Editoria11y issue counts on the Drupal main dashboard.

Remaining tasks

Determine which fields are needed. Write update hooks to modify tables and update the API. Write views connector hooks.

I will probably tag a 3.x branch in 2025 for Drupal 12 compatibility. That would be a very good time to include changes of this complexity.
