Visual tweaks to the fee selector in the send form

These are purely cosmetic adjustments:

- Make the font size of the selector the same as other send form fields
- Lighter color for the option durations
- Various spacing tweaks for a more harmonious appearance

There are still some very minor details like item height, hover state, etc that we may tweak further as make our design system consistent. But these tweaks here get us very close.
