This should implement #332

Things I definitely want others' input on:

• The code for is_bankruptcy, which I went with what SEEMED correct, but I could be very wrong (see comment in that function).
• The new templating code that now supports Django templates (see notes below).
• A little bit more strict typing in the CL api code (just to give me some extra insurance that my code was correct).
• I didn't add any new tests to the test_tasks.py file. Not sure if that would be good as well, or would overlap a ton with the tests in test_templates.py that I added.

For the template code, as I was adding the desired feature, I experimented with a few different ways of doing it. I first attempted to continue our current path of 1 template per option. Since before we only had one option, that was fine since that only meant two templates. However I discovered this grows exponentially. 2 options means 4 templates (e.g., post, post w/ article, post w/ date, post w/ article + date). And 3 options means 8 templates.

This was starting to get unwieldy (especially for the code for deciding which template to use). I also thought about adding something like sub templates where you could inject templates into other templates for some of this conditional stuff. This just felt like writing my own templating engine (poorly). My next experiment was trying to do a lazy loaded f string so I could use f string conditionals in the templates. This proved to be a bit unwieldy as well since to do so I would either have to make the template strings into lambda functions (which seemed funky) or you can populate an f string by passing it into eval (which sounds like a security nightmare waiting to happen).

So ultimately the only other choice I could think of boiled down to "use a template language" and since we're using Django, we essentially get one out of the box.

However I know that this may feel like overkill, and others may not share my opinions and evaluations of the other solutions, or even come up with a solution that I didn't think of. So this part is definitely flexible. I just wanted to get something working and in front of you and then iterate from there if needed.
