C11 is the P1P, C12 the P1S, C13 the X1E and N7 the P2S, as the virtual
printer and a real P1P 3MF already say. The frontend map had them shifted,
so discovery pre-filled a P1S as a P1P and an X1E as a P2S. The backend
map read C11/C12 as X1C/X1 and lacked N7, the firmware check sent C13 to
the P2S line, and the capability lists never matched BL-P001 because
their lookup strips the dash.

Post work PR #3134
A queue item's "Any <model>" button labeled itself from the file's slice
metadata while the scheduler used the row's target_model, so an X1C-sliced
item targeting H2D showed "Any X1C" above "assign to first idle H2D". The
mismatch itself was created silently: sliced-for metadata loads async, and
switching to model mode before it arrived pre-selected the alphabetically
first model (H2D on a mixed farm), after which the model dropdown hid
itself. Nothing validated compatibility, so the scheduler would hand X1C
G-code to an H2D.
Frontend: never default the target silently, keep the dropdown visible in
model mode (incompatible models disabled), label from the actual target,
warn on mismatch, block submit when incompatible.
Backend: new GCODE_COMPAT_FAMILIES table (X1/X1C/X1E/P1P/P1S interchange;
everything else exact-match; missing metadata never blocks). Queue create
and update reject incompatible targets with 400; the scheduler holds back
pre-existing mismatched rows with an actionable waiting_reason instead of
dispatching them.
