Same treatment as AlbumApplicationResponse, but Track is the cleaner
case: OwnerUserId (local-only) and ExternalId (external-only) are
both genuinely exclusive to one side, so the base carries neither and
is abstract — every real value is one of the two derived types.
TrackApplicationResponse (abstract, shared fields + FromEntity dispatch)
LocalTrackApplicationResponse (+ OwnerUserId)
ExternalTrackApplicationResponse (+ ExternalId)
Hit a real gotcha along the way: the response already had an explicit
Source property, which collides with the "source" discriminator STJ's
polymorphism support injects ("contains property 'source' that
conflicts with an existing metadata property name" — only surfaced at
runtime in the Api integration tests, not at build time). Fixed by
dropping the now-redundant explicit Source field entirely; the
discriminator already serializes the identical "Local"/"YouTube"
value under the same name, so the wire contract is unchanged. Updated
the two call sites that read .Source directly (TrackSearchItemResponse
and a playlist track filter that needed flatMap instead of
filter().map() to keep the narrowing across the chain).
