Migrate the IDEX/IQEX config keys testers already have

Browse Source 
The parallel printing options shipped to testers as is_ixex and ixex_*,
became is_imex and imex_* when the feature stopped being called iXex, and
the two clearance keys were renamed once more to say what they measure:
nozzle to carriage edge on the collision side, not the carriage's full
width. Nothing translated any of it, so loading an existing printer profile
dropped every one of these values - the keys are unknown and cleared.
is_ixex is the one that matters most, because without it the others migrate
into a feature that stays switched off, leaving settings that look
configured and do nothing.

Per-plate mode is persisted twice and only one path went through
handle_legacy. Plate metadata in a 3MF is matched by exact attribute name
and written with set_key_value, so a project saved between the per-plate
mode landing and the rename loaded every plate back on Primary and sliced
single-carriage with no warning. The loader now accepts the old attribute
name.

ixex_primary_col and ixex_primary_row are dropped rather than mapped: the
primary is a role inside the mode's active-tools string now, not a grid
coordinate, and they were never in an option list, so no saved file carries
them.

The test drives the full era-1 key list and asserts the enum values rather
than non-nullness, since a forward-compatible substitution would otherwise
hide a failed deserialize behind a default. handle_legacy had no test before
this.
