Widgets: Update test images

Some Samsung phones were allowing graph widgets to occupy 1x2 or
2x1 grid cells, leading to very small text. This commit bumps up
the minimum widget size to 100x100 to ensure they always occupy at
least 2x2 cells. Tested on Pixel 4, Pixel 7 and Samsung Galaxy S24.

Closes #2118
