fix: show the full description of space permissions

The description of a role in the space member permissions list was
capped at two lines with a middle ellipsis. Android only applies a
middle ellipsis to single-line text, so longer descriptions such as the
one for "Can manage" were silently cut after the second line.

The description now has room for four lines and uses an end ellipsis,
which Android does apply to multi-line text, so anything longer is
visibly truncated instead of hidden.
