Fix pageviews slider

[apata]

Changes

• Fixes the pageviews slider on Firefox by aligning the base of the range input with the base of various texts that appear next to it.
  • For that, it needs to have same top and bottom margin and vertical-align: middle, which I opted to give using style not TW classes, just to keep it the same as in website #pricing section.
• Stops slider output text from wrapping around the 1024px screen width mark by changing the font size and removing custom large screen horizontal padding from choose plan page.
