Make the BodyCaptcha editor window scale and resize

[ii-impy]

What

bodycaptcha_editor.py opened a fixed, non-resizable window that renders very small on a HiDPI display.

-        self._surf    = pygame.display.set_mode((W, H))
+        self._surf    = pygame.display.set_mode((W, H), pygame.SCALED | pygame.RESIZABLE)

Why

Two separate causes, both at set_mode:

• Small: W, H = 1060, 700 assumes a ~1080p display. On a 3072x1920 panel under Wayland/XWayland with xwayland-native-scaling enabled, SDL reports the desktop at full native resolution and nothing upscales the window — so it is 1060x700 physical pixels, about a third of the screen width.
• Not resizable: no RESIZABLE flag, so the window manager has no resize handle.

SCALED is the right lever rather than RESIZABLE alone: the layout is computed from the W/H/GRID_W constants throughout (_cell_size, _grid_origin, _thumb_rects), so a bare resizable window would leave a 1060x700 image in the corner of a larger frame. SCALED keeps that math intact and lets SDL scale the result.

The two sibling tools (app.py, body_grid_tester.py) avoid this by running FULLSCREEN | NOFRAME; the editor was the only one showing a fixed windowed size.

Testing

• Verified on a 3072x1920 display: SDL now opens a 2120x1400 window over the 1060x700 render surface, and the window resizes.
• Grid clicks confirmed working in the running editor. Mouse coordinates arrive via both ev.pos and pygame.mouse.get_pos(); SCALED translates both back into surface space, so hit-testing is unaffected.
• test_bodycaptcha_levels.py passes (7 tests). Note it covers level data, not the display layer — there is no automated coverage of this line.

No open issue tracks this; found while running the editor locally.
