Finalize Details, maybe fix endo issue?

Details

Pretty up the Details section, including wiring up media:

Fonts/endos

I think loading all the fonts and setting the CSS to use them seemed to fix the problem? I confirmed that it's not coming from the image, will explain in comments below

I may have gotten the fonts to work w/o images but it's late and needs more testing.

I pushed up one more commit for you to test on:

1. in your dataset, change one of the problematic fonts (Sylheti maybe?) to have nothing in the Font Image Alt column
2. upload to mb
3. go to deploy url: https://deploy-preview-69--languagemapping.netlify.app/
4. does the font show in Details??? you can confirm it's not an image by highlighting a character:

if so then i think it's working w/o image.

Wowww if that's the case! I 100% did not expect it to work like this.

If it IS working then I'll adjust to make ASL/mongolian work again along w/showing the native endo in popup, tooltips, table, etc.

if it's working and we've confirmed it then... really sorry you had to go through 1 million steps!

if it's not then... thanks for uploading all those SVGs :)
