URL Normalization

From the linked article originally in a comment in #85
Django docs on normalizing URLs

Both of these options are meant to normalize URLs. The philosophy is that each URL should exist in one, and only one, place. Technically a URL foo.com/bar is distinct from foo.com/bar/ – a search-engine indexer would treat them as separate URLs – so it’s best practice to normalize URLs.

Since SEO is important, shall we change this to True?
Maybe add PREPEND_WWW too?

I did add APPEND_SLASH (on feat/1_auth) before but couldn't get expected result so I implemented a solution on the front-end which is not ideal.
Let's go over this during the meeting.

Setting it to false makes Django not normalize URLs to have an ending slash

Setting it to true would help in some cases, for example the confusion caused in #166
