Remove legacy backend/workspace, add preferences UI

Refactor UI and build sources: remove legacy backend/workspace/image-list/save/vulkan-window modules and update CMake source lists accordingly. Move/centralize preferences UI into imiv_aux_windows.cpp (theme, pixel view, image rendering, OCIO config, backend selector, memory, slideshow and close behavior) and update documentation to reference imiv_vulkan_setup. Add image export/save and OCIO-aware processing routines to imiv_file_actions.cpp and adjust includes across several modules to use imiv_viewer/imiv_workspace_ui. Overall cleanup to consolidate preference, export, and backend selection logic and remove obsolete files.
