fix: modal windows now have the Qt.Dialog flag

Set the Qt.Dialog flag for modal windows, such as "Add Field" so that
they will be seen as dialogs in the backend. This change is unlikely to
be at all noticeable in systems like Windows, but for users running
tiling window managers like bspwm or Sway, this will prevent these modal
windows from being tiled alongside the main window, instead they will be
floating on top, which is the expected behaviour seen on floating window
managers, like the ones used by Windows and macOS.

Added self.setWindowFlag(Qt.Dialog, on=True) # type: ignore to the
following files:
- tagstudio/src/qt/modals/add_field.py
- tagstudio/src/qt/modals/delete_unlinked.py
- tagstudio/src/qt/modals/drop_import.py
- tagstudio/src/qt/modals/file_extension.py
- tagstudio/src/qt/modals/fix_dupes.py
- tagstudio/src/qt/modals/fix_unlinked.py
- tagstudio/src/qt/modals/folders_to_tags.py
- tagstudio/src/qt/modals/mirror_entities.py
- tagstudio/src/qt/widgets/paged_panel/paged_panel.py
- tagstudio/src/qt/widgets/panel.py
- tagstudio/src/qt/widgets/progress.py

Note that without adding # type: ignore, MyPy *will* give out an error,
presumably because PySide6 is missing type hints for several things, and
this may *or* may not be a justifiable use of # type: ignore, which
throws the MyPy type checking for that line out the window.
