fix(groups): inset Requests headers and lead Join Requests with the key note

The Requests screen's "Waiting on you" and "Sent" headers sat flush with
the screen edge: SectionHeader sets only vertical padding. They now take
the rows' inset.

Join Requests showed "Approving shares the group key with them from this
device." under the list. iOS shows it above the rows, so it is read before
Approve; Android now does the same, with iOS's 4/12 spacing.
