Inconsistent UI elements and some issues

[jermanuts]

1. In Launcher

Both buttons don't have the same height, there are multiple instances of same inconsistency of height in other pages.

2. Refresh icon is not centrally aligned

3. Click on avatar icon -> Profile, click on "Share"

The 'X' is way far from its own window.

4. In Profile, "Biography" have a weird behavior when you click/type

Also, in Profile, both are not aligned correctly

5. The X button should be white on dark theme (inconsistent, some pages have it white and some not), when searching

6. Calendar doesn't have dark mode.
