The tray reader kept material, colour, profile and amount but dropped the
spool's RFID fields, so the printer test couldn't have shown a filament's
serial even if the printer sent one. It now keeps tray_uuid (the spool),
tag_uid (the tag) and tray_id_name where the firmware provides it, and turns
the all-zero values sent for untagged spools into "none" rather than a fake id.
The printer test also takes ?debug=1, which returns one loaded tray exactly as
the printer sent it, to see which fields a given printer and firmware provide
before designing around them. It's filament data; no credentials are in it.
Also notes that an AMS lite's "remain" is full-or-empty rather than a
measurement, which the next change needs to account for per printer.
