Kris Austin 6fda82476d fix: out-of-bounds read computing tool-ordering max layer height (#14665) ...

* fix: out-of-bounds read computing tool-ordering max layer height

calc_max_layer_height() loops over the extruder count (nozzle_diameter)
but indexes max_layer_height with the same counter, reading past the end
when that array is shorter. Silent on release builds, aborts under a
bounds-checked STL (_GLIBCXX_ASSERTIONS).

Read via get_at(), which falls back to the first entry when the index is
out of range, as Slicing.cpp already does for this option.

Add a fff_print regression test slicing a two-extruder printer with a
single-entry max_layer_height.

* docs: clarify how max_layer_height ends up short in the regression test

Normalization sizes it to the filament count under single_extruder_multi_material,
not "a mismatch a profile can ship" as the earlier comment guessed.
