epriestley 3b1294cf45 Store Phriction max version on Document, improve editing rules for editing documents with drafts
Summary:
Ref T13077. We need to know the maximum version of a document in several cases, so denormalize it onto the Document object.

Then clean up some behaviors where we edit a document with, e.g., 7 versions but version 5 is currently published. For now, we: edit starting with version 7, save as version 8, and immediately publish the new version.

Test Plan:
  - Ran migration.
  - Edited a draft page without hitting any weird version errors.
  - Checked database for sensible `maxVersion` values.
