Add encrypted admin w/"no count" pagination

[aclark4life]

Existing approaches to "no count" pagination do not seem to include support for pagination in the Django admin, so:

• Subclass Django's core Paginator

  • override count

• Subclass Django's contrib admin view ChangeList.get_results

  • Use len instead of count
  • Ruff fixes for try/except

• Subclass Django's contrib ModelAdmin

  • override get_paginator
  • override get_changelist

As I said before, len(queryset) will load the entire collection into memory. If MongoDB is supposed to be for big data, this is a nogo. It will likely take a long time and/or cause the app server to run out of memory.

Perhaps it works for testing a toy project with a small collection, but I'm unsure we should ship this approach to enterprise customers. We can check with the team before investing more time, like adding tests.

We should not ship a toy to the enterprise but we should figure out how to implement this feature so folks can use the Django admin.
