Standardize endpoint url format on trailing slashes

Currently if the front-end makes an API request to the backend, the url needs to be an **exact match** in order to get a response otherwise it returns a 500 TemplateDoesNotExist exception or a Forbidden (403) error.

I experienced this issue when creating a test endpoint with the url `localhost:8000/endpoint` and tried making requests to `localhost:8000/endpoint/`. Similarly, the same error happens when the endpoint url is `localhost:8000/endpoint/` and a call to `localhost:8000/endpoint` is made.

1. There should be a standard for whether we include a trailing slash or not in the django urls.py files. As an example server/api/views/jira/urls.py has no trailing slashes for any of the endpoints, server/api/views/listMeds/urls.py has trailing slashes, and server/api/views/chatgpt/urls.py has _both_ trailing slashes and no trailing slashes in the urls
2. There should be a way to automatically redirect a url with or without a trailing slash to the correct endpoint. According to the [Django docs](https://docs.djangoproject.com/en/dev/ref/settings/#append-slash), this error shouldn't be present. I'm not entirely sure why it isn't working here.
3. On the front end, it could be beneficial to create a `apiClient.ts` file that contains every axios api request and react components can import the necessary functions rather than write them internally. This would help with standardizing api requests from the front-end

I'm also unsure as to why for some incorrect url calls, it returns the 500 TemplateDoesNotExist exception vs. Forbidden (403) error. However the fix should address both of these.
