Bugfix: Fix emoji icon scaling

[julian-wls]

Problem Description

Currently, the icon for the add emoji button seems a bit too big and not aligned, see screenshot:

It looks fine when the text size is bigger than usual, but not with the normal scaling.

Changes

This PR changes the height of the emoji to use .sp to be affected from the font changes and therefore be aligned with the other emoji chips.

Steps for testing

Make sure it looks good before and after changing the font size.

Nice change, there are two issues I noticed:

1. For small font sizes, the emojis and counter seem to be not centerred anymore
   
2. For very large font sizes, the icon is still a little bit smaller than the emojis

Good catch, I managed to fix it for the very small font sizes.
For the large font sizes, I'm not quite sure, when selecting the largest it seems aligned correctly for me:

Hm interesting, I re-tested on both foldable and physical device, and in both cases the icon size was off for the largest font size🤔

Oh, okay. I was using the font scaling in the accessibility options of the Android system settings app. There seem to be only 5 different text sizes, which all look good now.

Uh good to know. I just checked in the Android settings, there are two different scales. Display size apparently controls the .dp scalings, and font size the .sp scaled elements.

Oh, I only had 4 steps on the font scale (API 33):

I tested on API 35, and it works with the ultra big font size now :)
The solution was to change the padding of the box to also use .sp.
