Tab names of modals not vertically centered

The tabs names of a lot of modals are not vertically centered which looks weird.

Example modals:

• Recordings->Events->"Event Details"

• Recordings->Series->"Series Details"

Likely others, too.

The reason is that for some languages, the tab names are taking up two lines. In that case, the tab names are centered.

It should, however, be implemented correctly for single-line tab titles, too.
