Jellyfin and Emby sessions expose Client and DeviceName but no platform,
so dashboards and session trackers (Tracearr's normalizeClient, for one)
keyword-match the Client string the way they do for "Jellyfin Android TV"
and "Swiftfin tvOS". Plezy sent Client="Plezy" on every platform, so every
install showed up as platform "Plezy", and an unresolvable device name
became Device="Plezy" as well.
Add jellyfinClientName, which appends the platform ("Plezy Android TV",
"Plezy tvOS", "Plezy iOS", ...), and jellyfinDeviceName, which falls back
through the hardware model and the platform before the app name, and use
both at the two Jellyfin/Emby header call sites. Every emitted client
string was checked against Tracearr's matcher. The Plex headers and the
DisplayPreferences client key are unchanged.
