Add a Font Selection Option in Profile Settings

Foreman recently changed the application font, and the new font feels harder to read than the previous one. The main issue is readability in data heavy areas such as the Miners tab, tables, and the main dashboard. In views where a lot of values are grouped together, the text seems to blend together more than it did before. This makes it harder to quickly scan the page, spot issues, or find specific information.

One possible place for this option could be under My Account, near other user-specific preferences such as Timezone, Fiat Currency, and similar display-related settings. That way, the user can choose to go back to the old font.
