Jellyfin - Use API key instead of username/password

[SpeakingOfBrad]

Description

Jellyfin has an API and it's very easy to request (and control) an API key that could be used by Homarr.
All of the *arr integrations already use an API key for access, and Jellyfin should too.

Priority

Low (Nice-to-have)

This would be really cool, otherwise I will always have one user just for Homarr.

I love to have this. I am using Jellyfin without a password and I can't add integration to homarr without password unfortunately.
