feat(gui): add optional tkinter and Qt6 desktop dashboards
Add two optional windowed frontends over the same local state the TUI and
web console read: `enodia-sentinel gui` (stdlib tkinter) and
`enodia-sentinel gui-qt` (PySide6, new `[qt]` extra).

Both share `gui/model.py`, a GUI-free presentation model over
`tui.collect_model`, so every formatter is unit-testable without a display
server. Only `app.py` and `qt_app.py` import GUI libraries, enforced by
import-guard tests mirroring the tray applet's boundary.

Tabs cover status, alerts, incidents, posture, integrity, response plans,
and the event tail, plus daemon-control buttons via systemctl. Response
plans are display-only; the GUIs never execute containment commands. Core
runtime dependencies stay empty.

"""Desktop GUI shell for Enodia Sentinel (tkinter only).
This module is the only part of the GUI package that imports ``tkinter``.
All presentation logic lives in ``model.py`` so it can be tested without a
DISPLAY. The GUI is read-only for response plans: it displays suggested
containment/recovery actions but never executes them.
