fix: remove unnecessary hook

[iamacook]

What it solves

Resolves unnecessary hook

How this PR fixes it

The TxStatusWidget no longer requires useDarkMode to set the colour of the badge. Instead it now uses the data-theme attribute.

How to test it

Create a transaction and switch between the light and dark mode. Observe the badge colour changing correctly.
