Old behavior:
Session recording links pointed at the Meetecho player for every session with a timeslot. When meetecho_recording_name was empty, the datatracker made up a name from the group acronym and the start time. That produced dead links for sessions that were never recorded (e.g. IESG telechats), for recordings still being processed, and for sessions that have not happened yet.

New behavior:
Makes the field meetecho_recording_name (set by Meetecho through /api/meeting/session/recording-name once recording is available) the only source for the link:

• Session.session_recording_url() returns None when no recording name is set. The made-up fallback name (_session_recording_url_label()) is removed.

Fixes #9592
Fixes #10541
Fixes #10555
Fixes #8237

Related fix in this PR:

• The "Session recording" button and dropdown item in session_buttons_include.html are shown when there is a recording URL, not when the session had a live video stream. A live stream does not mean a recording exists.

relates to #11572

[rudimatz]

keeping this as draft until backfilling script from #11932 ran

[rudimatz]

the backfill script ran on both staging and prod. This logic to stop guessing recording names can now be applied.

[rudimatz]

to test after deployment: the link to "Meetecho session recording" for these will be removed, since no recording exists
