Allow resizing the drop-down terminal by dragging its bottom edge

closes #2337

Summary

Similar to Windows Terminal, this lets you resize Guake's drop-down window by dragging its bottom edge — handy for temporarily expanding the terminal to read long command output without leaving the drop-down view.

• Enable decorated on the main window (guake.glade) so the window manager provides a native border, which makes it grabbable/draggable on the bottom edge.

• Debounce configure-event on the main window (300ms) to detect when a drag-resize has settled, and record the resulting height/width as percentages of the monitor workarea (Guake.on_window_configure / on_resize_debounced in guake_app.py).

• Store that as an in-memory SettingsOverride (guake/utils.py) that RectCalculator.set_final_window_rect prefers over the persisted window-height/window-width gsettings values, without writing them back to gsettings — so the size holds for the rest of the session (surviving hide/show via F12) without permanently changing your configured default.

• If you explicitly change height/width/alignment via Preferences, accel_increase_height/decrease_height, or dconf, the override is dropped (GSettingHandler.size_changed/alignment_changed in gsettings.py) so the persisted setting takes priority again, as expected.

Notes

• The Fluxbox show() workaround previously re-triggered the window-height changed signal to force a re-apply; that would now also clear the override, so it was changed to call RectCalculator.set_final_window_rect directly instead, preserving the original Fluxbox fix without disturbing the in-session override.

• Also bumped the black/flake8/pylint pre-commit hook revisions, which were badly out of date and crashing under modern Python (old black referenced ast.Str, removed in Python 3.12+).

Testing

• make style check test
• Manually: drag the bottom edge to resize, hide/show (F12) and confirm the size sticks; then change the height via Preferences and confirm that takes over cleanly.

I notice from both my testing and your video that this change introduces an unnecessary titlebar. That's going to have to get cleaned up before I merge this.

[anhtumai]

Thank you for your respone. I will look at it tonight or this weekend

[anhtumai]

@Davidy22 I have fixed the code.
Here is the new demo , when I have removed the title bar. You can check in guake.glade that the code is same as before, except for glade version changed

About the title bar, actually I prefer to keep it, because it has options to: Move to monitor (Up/Down/Left/Right). So we can move the Guake terminal to other places, not stuck in one place. What do you think about this @Davidy22 ?

If you agree, I will keep the titlebar, since it improves user experience a lot

Another solution is to make another issue to fix: Move Guake terminal to wherever cursor last clicks, but it will be much harder to do than just enabling the titlebar by setting: decorated=True
