Summary:
Adds a second line of text under icon/doc icons for more clarity.
Will stop at two lines; if text continues, it will be elided.

BUG: 362986

Test Plan:
- Install Application Dashboard, identify a one-line elided item
- Apply patch and compile
- Check that item text is now two lines but does not overlap next row
