pax c4efdb76f8 Drop refactor re-export shims, update imports to canonical locations
Final commit of the gui/app.py + gui/preview.py structural refactor.
Updates the four call sites that were importing through the
preview.py / app.py shims to import from each entity's canonical
sibling module instead, then deletes the now-empty shim files.

Edits:
  - main_gui.py:38      from booru_viewer.gui.app import run
                     →  from booru_viewer.gui.app_runtime import run
  - main_window.py:44   from .preview import ImagePreview
                     →  from .preview_pane import ImagePreview
  - main_window.py:1133 from .preview import VIDEO_EXTENSIONS
                     →  from .media.constants import VIDEO_EXTENSIONS
  - main_window.py:2061 from .preview import FullscreenPreview
                     →  from .popout.window import FullscreenPreview
  - main_window.py:2135 from .preview import FullscreenPreview
                     →  from .popout.window import FullscreenPreview

Deleted:
  - booru_viewer/gui/app.py
  - booru_viewer/gui/preview.py

Final gui/ tree:

  gui/
    __init__.py            (unchanged, empty)
    app_runtime.py         entry point + style loader
    main_window.py         BooruApp QMainWindow
    preview_pane.py        ImagePreview embedded preview
    info_panel.py          InfoPanel widget
    log_handler.py         LogHandler (Qt-aware logger adapter)
    async_signals.py       AsyncSignals signal hub
    search_state.py        SearchState dataclass
    media/
      __init__.py
      constants.py         VIDEO_EXTENSIONS, _is_video
      image_viewer.py      ImageViewer (zoom/pan)
      mpv_gl.py            _MpvGLWidget, _MpvOpenGLSurface
      video_player.py      VideoPlayer + _ClickSeekSlider
    popout/
      __init__.py
      viewport.py          Viewport NamedTuple, _DRIFT_TOLERANCE
      window.py            FullscreenPreview popout window
    grid.py, bookmarks.py, library.py, search.py, sites.py,
    settings.py, dialogs.py    (all untouched)

Net result for the refactor: 2 god-files (app.py 3608 lines +
preview.py 2273 lines = 5881 lines mixing every concern) replaced
by 12 small clean modules + 2 oversize-by-design god-class files
(main_window.py and popout/window.py — see docs/REFACTOR_PLAN.md
for the indivisible-class rationale).

Followups discovered during execution are recorded in
docs/REFACTOR_NOTES.md (gitignored, local-only).
