"""Profile defaults per product (#1326).

A default holds the slicer preset, the per-model preset overrides and the K
profiles for one Brand/Material/Subtype, for all colours or for one, and every
way a spool is added copies it onto the new spool. Both inventory modes; the
default itself is shared.
