Fix: resolve 23 MSVC compiler warnings (#15280)

* fix: resolve MSVC compiler warnings and build error

C4101 - unreferenced local variables:
  - STEP.cpp, FilamentGroup.cpp: remove unused catch variable 'e'
  - GLGizmoMeasure.cpp: remove unused 'direction_on_model'
  - PartPlate.cpp: remove unused 'origin1, origin2'
  - DevStatus.cpp: suppress unused 'e' via (void)e

C4005 - macro redefinition:
  - Wrap NOMINMAX defines in #ifndef guards (OrcaSlicer.cpp, Preset.cpp,
    SupportTreeBuilder.cpp, OpenVDBUtils.cpp, GUI.cpp)
  - Remove conflicting DESIGN_INPUT_SIZE redefine in DownloadProgressDialog.cpp

C4172 - return address of local/temporary:
  - Config.cpp: return static const double instead of temporary 0

C4996 - deprecated API usage:
  - ImGuiWrapper.cpp: use GetText().Length() instead of GetTextLength()
  - OrcaCloudServiceAgent.cpp: replace deprecated wxPATH_NORM_ALL with
    explicit flags matching old default behavior
  - ASCIIFolding.cpp: replace deprecated std::wstring_convert/codecvt_utf8
    with boost::locale::conv::utf_to_utf (already used in same function)

C2440 - build error from deprecated wxTipWindow constructor:
  - Button.hpp/cpp: replace raw wxTipWindow* with wxTipWindow::Ref (weak
    reference). Ref auto-nulls when the tip window closes, eliminating
    the manual Bind(wxEVT_DESTROY) handler. delete uses operator->() to
    access the raw pointer since Ref is non-owning

* fix: avoid duplicate GetText() call in ImGuiWrapper clipboard handler

Capture wxTextDataObject::GetText() result in a local variable instead
of calling it twice (for .Length() check and into_u8()). GetText()
returns wxString by value, so this avoids an extra allocation/copy.
