Move 10 media loading methods (_on_post_activated, _on_image_done, _on_video_stream, _on_download_progress, _set_preview_media, _prefetch_adjacent, _on_prefetch_progress, _auto_evict_cache, _image_dimensions) and _prefetch_pause state into gui/media_controller.py. Extract compute_prefetch_order as a pure function for Phase 2 tests. Update search_controller.py cross-references to use media_ctrl. main_window.py: 2525 -> 2114 lines. behavior change: none
