fix(typography): use monospace for dynamic numeric values

[0xdeafbeef]

Description

The CPU temperature kept changing width and making the bar jump around, which was pretty distracting.
This switches dynamic numbers in DankBar to the configured monospace font so the layout stays stable.

We dont like this approach as much because it makes the fonts inconsistent, the intended behavior that may not be working correctly is to use TextMetrics to basically keep a minimum width for the largest possible value, that way the text changes but the overall widget size stays the same

@bbedward

TextMetrics keeps the widget’s outer width stable, but the proportional digits still visibly shift within that fixed space.

Mono keeps both the widget width and the digit positions stable :)

BTW

Qt supports font.features: { "tnum": 1 }, and the bundled Inter font has tabular numerals, so that might make both of us happy :) We can keep the intended font consistent while preventing the digits from visually jumping around.

Should i open an issue? I can make a pr latter
