feat: Make courseware URLs more human-readable

[KristinAoki]

This PR updates the format of MFE URLs. Previously the URLs were extremely long and had repetitive information. This made it difficult for users to read and easily understand where they are within a course based on the URL. Now, the URL removes all the repetitive information and replaces it with a unique identifier. Updated all API call URLs with a decoded version of block id since unique identifier is being pulled from URL, but does not translate to any API in LMS.

I'm gonna close this PR - it's definitely not going to be merged after all this time. Would still be nice to see something like this done eventually though.
