Fix Jellyfin API compatibility

[diegodorado]

Summary

• Fix Jellyfin API compatibility for library discovery and authentication.
• Use Jellyfin's /Library/MediaFolders endpoint instead of the Emby /Users/{id}/Views endpoint.
• Update Jellyfin authentication to use the Authorization: MediaBrowser ... header format and avoid requiring a Jellyfin user ID.
• Add dialect-specific library path handling while keeping the common client logic shared with Emby.
• Fix q handling in the setup result screen so it properly quits instead of returning to the setup menu.

Testing

• Verified Jellyfin authentication and library access against Jellyfin 10.10.7.
• Verified album and track retrieval through the Jellyfin API.

Summary by CodeRabbit

• New Features

  • Improved Jellyfin compatibility for sign-in, server detection, and music library browsing.
  • Added support for Jellyfin’s library paths and authorization requirements.
  • Library loading now works consistently across supported media servers.

• Bug Fixes

📝 Walkthrough

Walkthrough

The setup wizard now treats q as a quit command. The media API delegates library paths to provider dialects and updates Emby URL escaping and Jellyfin authentication, ping, user discovery, and library endpoints.

Changes

Setup navigation

Layer / File(s)	Summary
Result-stage exit handling cmd/setup.go	The result stage exits on q and returns to the provider menu on enter, escape, or space, including after save validation fails.

Media API dialects

Layer / File(s)	Summary
Dialect-specific library routing internal/embyapi/dialect.go, internal/embyapi/client.go, internal/embyapi/client_test.go	The dialect interface provides library paths. Emby escapes user IDs in its views path. Jellyfin uses MediaBrowser authorization, /System/Info, and /Library/MediaFolders. Tests verify the updated requests and headers.

- Around line 1038-1039: Update the input handling around the awaitingSave
branch so pressing q returns tea.Quit even when awaitingSave is true; preserve
the existing behavior for other keys and add a regression test covering this
state.

In `@internal/embyapi/dialect.go`:
- Around line 109-110: Update TestJellyfinAuthHeaderScheme to accept the
/Library/MediaFolders request in its mock routing, while preserving the
Authorization header assertion for that request and the existing handling for
/Users/Me and /Users/user-1/Views.

existing save and cancel options, while preserving current behavior for other
states. Add a regression test covering the awaitingSave prompt output.

In `@internal/embyapi/client_test.go`:
- Line 130: Update the Authorization assertion in the /Library/MediaFolders
request test to require the configured token value, such as Token="tok", in
addition to the existing MediaBrowser prefix check. Use the test’s preconfigured
token when validating the header so missing or altered credentials fail the
assertion.
