Make filament compatibility temperature-aware (#13522)

Browse Source 
* Make filament compatibility temperature-aware

Extend filament compatibility checks to consider actual nozzle temperatures and temperature ranges.
Print::check_multi_filaments_compatibility now accepts nozzle temperatures and range lows/highs; it resolves missing ranges from material defaults, computes per-filament effective temperatures, and checks pairwise compatibility (including high/low/mid mixed cases).
Updated callers in Print::check_multi_filament_valid and CalibrationWizardPresetPage to pass nozzle settings, consolidated user-facing warning strings, and fixed extruder index handling and minor logic/path improvements.

Clarify incompatible nozzle temperature warnings

* Update Print.cpp

* Remove json usage

* Reduce messages
