fix: keep calendar RSVP buttons on a single line

The Going / Maybe / Can't go buttons in the calendar feed card wrapped
to two lines because the default button content padding (24dp horizontal)
left no room for "Can't go" in an equal-weight third of the row.

Tighten the content padding, shrink the row spacing, and constrain each
label to a single line so the three buttons fit horizontally.
