Add text-shadow to app.css to improve readability

Addresses suggestion made in request #198

Thank you for your contribution. We are mostly using tailwind for our CSS. What are your thoughts on a custom CSS file that you can map to your container to edit/override and customize your immichFrame?

If you guys are completely against the idea of text shadows, then a custom CSS is definitely the next best option. I tried adding it to tailwind but couldn't get it to work. I'm really outside my comfort zone here.

Found a technical write-up on it but I'm exhausted and can't think straight right now. Might have a crack at it tomorrow.

Thank you for the change and the resources. Do you mind adding it for the Clock too? I like the work :)

[iCanHazSkillz]

Thank you! I went ahead and created 2 classes to accommodate shadows on both small and large text and applied it to the clock as well.

Let me know if there should be anything else added.

I think there happened something when pulling from main. Your code contains some of the new stuff but not everything and does not build anymore :P
