The player's "source" link only worked for direct yt-dlp URLs. Two other
cases had no linkable page: ListenBrainz picks resolved via ytsearch1: (the
locator is a search query) and Subsonic library tracks (an opaque song id).
Centralise the rule in Track.page_url and cover both: the yt-dlp fetcher now
records the concrete video URL it resolved into source_url, and a Subsonic
track links to the stream's new /share endpoint, which asks ingest to mint a
public share (createShare) on demand and redirects to it — so a share is only
created when a listener actually clicks, never per played track.
