fix: cache Jellyfin/Emby avatars from API (fallenbagel#1045)

* fix: cache Jellyfin/Emby avatars from API

Previously, avatars were cached using image links from Jellyfin/Emby. Now, avatar images are
obtained directly from the API to avoid some configuration bugs.

* fix: update avatar on new login
