Spoolman leads CC2 Control's copies; new spools from the bridge

- Master data of CC2 Control's copies follows Spoolman (name, brand,
  colour, diameter, density, net, tare, price; not the material, which was
  fitted to the tray).
- A loaded spool's rest in CC2 Control is set to Spoolman's via
  /api/spools/adjust once everything is booked (old copy after the roll
  printed in the other printer, weigh-in in Spoolman); the resulting
  correction is not booked back.
- Copies of spools archived or deleted in Spoolman are deleted from CC2
  Control when no tray holds them (library limit 128); an outage never
  counts as deleted.
- A roll that ran out is archived in Spoolman (setting, default on); a
  scan of an archived spool maps nothing.
- A roll scanned again with unchanged tag data and put back into its old
  slot (after printing in the other printer) is recognised.
- Tag generator: "Neue Spule" creates spools in Spoolman from an existing
  or a new filament (and vendor), labelled vendor + id, then opens the tag.
