Show the server-provided name for plugin tuner types

[vk496]

Changes

The tuner device card resolves its title from a hardcoded type list (getTunerName) and shows "Unknown" for any type not in it, including plugin-provided tuners. This uses the display name returned by the TunerHosts/Types endpoint via a small useTunerHostTypes hook, keeping getTunerName as a fallback while the query loads.

A plugin can register an ITunerHost; it shows up by name in the "Add Tuner Device" dropdown, but once added the device card reads "Unknown". This makes the card match the dropdown.

Issues

Part of jellyfin/jellyfin#17372. The guide provider list has the same limitation but needs a new API, proposed in jellyfin/jellyfin#17371.

Verified against a live server: TunerHosts/Types returns { Id: "htsp", Name: "HTSP Tuner" } and the added tuner has no FriendlyName, so the card title resolves to "HTSP Tuner" instead of "Unknown". Production build succeeds with the change compiled into the Live TV chunk.
