Cliamp 2.2.0 cannot connect to Jellyfin 10.10.7 or 12

What happened

Cliamp 2.2.0 cannot connect to a Jellyfin server. cliamp setup fails with 400/401 responses and reports validation failed.

I initially suspected this was caused by Jellyfin 12's removal of legacy authentication, but the same problem occurs with a freshly installed Jellyfin 10.10.7 server.

I tested all three authentication methods supported by the cliamp setup:

• Jellyfin API token
• Jellyfin username/password
• Jellyfin user access token

None of them work.

The Jellyfin server itself is reachable and healthy. The same credentials can successfully authenticate using Jellyfin's HTTP API directly.

For example, a user access token successfully authenticates against /Users/Me:

curl -i \
  -H 'Authorization: MediaBrowser Client="curl", Device="curl", DeviceId="curl-test-1", Version="1.0.0", Token="ACCESS_TOKEN"' \
  http://localhost:8096/Users/Me

This returns HTTP 200.

An API token also successfully authenticates against a server-level endpoint:

curl -i \
  -H 'Authorization: MediaBrowser Client="curl", Device="curl", DeviceId="curl-test-1", Version="1.0", Token="API_TOKEN"' \
  http://localhost:8096/System/Info

This returns HTTP 200.

So the Jellyfin server, network connection, and credentials are working; the failure appears to be in cliamp's Jellyfin integration.

Steps to reproduce

1. Install Jellyfin 10.10.7 on macOS using the official DMG.
2. Start Jellyfin and configure a user and music library.
3. Run cliamp setup.
4. Configure the Jellyfin server URL.
5. Try API token authentication, username/password authentication, and a user access token.
6. Cliamp fails validation with HTTP 400/401 in all cases.

Expected behavior

Cliamp should authenticate with the Jellyfin server and successfully validate the provider configuration.
