Updates to Seerr image fetching (#1086)

## Description
This PR makes changes to how images are fetched for discover/Seerr
items.

If the discovered item is available on the Jellyfin server, the images
will be fetched from the Jellyfin server.

Then if the Seerr server has image caching enabled, the images will be
fetched from the Seerr server. Otherwise, images are fetched from TMDB .
TMDB was the previous behavior for all images.

### Dev notes

This PR also updates the Seerr server URLs stored in the database, so
it's not backwards compatible.

### Related issues
Fixes #1079

### Testing
Emulator against Jellyseer 2.7.3 & Seerr 3.0.1

## Screenshots
N/A

## AI or LLM usage
None
