fix: draw at monitor size, not a 1200x700 minimum

Hyprland's fullscreen rule resizes the window but not conky's drawing
surface, which stays at minimum_width/minimum_height. The dashboard
therefore painted its backdrop over roughly the top-left third of the
screen and left bare wallpaper beside it, visible as soon as the window
rules put it fullscreen on special:dash.

Set to the primary monitor, 2560x1080. The grid derives its cells from
the surface, so the layout still fills whatever size it is given; only
the surface needed to grow.

Task 4's development config keeps 1200x700 deliberately: a smaller
window is easier to screenshot and compare during that task, and it
never runs fullscreen.
