maziggy a9b57ccd3c Add variant-group endpoints and cross-model queue creation (#671, #2570) ...

Adds /library/variant-groups for declaring that several sliced files are
the same job for different printers, and a variants payload on queue
creation that turns such a set into one queue item with a candidate per
file.

The candidate set is validated as a set: one file per printer model, each
file sliced for the model it is offered as, and at least one model with
an active printer. A cross-model item deliberately holds no file of its
own, because print_queue.library_file_id is ON DELETE CASCADE and would
destroy the whole job when a single alternative is deleted.

Fixes internal printer-model codes never being resolved on queue create
and update: normalize_printer_model returns unknown input unchanged, so
the or-chain never reached the code map and a "C13" target matched no
printer and waited forever.

Skips candidates whose file is trashed or missing. Library deletes are
soft, and SQLite runs with PRAGMA foreign_keys off, so neither case is
covered by the schema; the hard-delete paths now also drop the rows.

Adds library_files.variant_target_model so a user can say which printer
a file without slicer metadata is for, kept out of file_metadata so the
assertion is never mistaken for parsed data.
