Extract image save logic into new module

Move all image save/export functionality out of imiv_file_actions.cpp into a new imiv_image_save.cpp/.h pair to separate responsibilities and reduce file size. Update imiv_file_actions.cpp to include the new header and remove the duplicated save/build helpers. Add imgui_stdlib (imgui_stdlib.cpp/header) to CMake source lists and use ImGui::InputText(std::string) in imiv_ui.cpp (replace manual buffer handling). Also add /bld to .gitignore and register the new source file in imiv_sources.cmake/CMakeLists.txt.
