Summary

Fix compilation errors on systems with GCC 15 and wxWidgets 3.2.4+ caused by ambiguous overload resolution.

Changes

PhysicalPrinterDialog.cpp: Explicitly specify std::vector<std::string> for set_values() call
Plater.cpp: Explicitly specify std::vector<fs::path> for load_files() calls (3 occurrences)

Root Cause

wxWidgets 3.2.4 introduced initializer list constructors for wxArrayString, creating ambiguity when the compiler must choose between std::vector<T> and wxArrayString for brace-enclosed initializer lists.

Testing

Tested on Arch Linux with GCC 15.2.1 and wxWidgets 3.2.9

Reference
