Manage entries at scale

- the admin uses the full window width, table cells stop wrapping
- columns sort by number, title, project, status, date and author
- filters sit in one row with search first and a page size next to them
- entries carry a real date: publish_at on create and change, publishing
  keeps that date, a date in the past publishes backdated
