Chat info / Group info: use full spacing between two title-less cards

ChatInfoView (Contact prefs/Send receipts/Chat theme → Delete messages) and GroupChatInfoView (Member reports → Edit group profile) both used SectionDividerSpaced(maxBottomPadding = false) = 10dp between two cards that have neither header nor footer touching the gap, so the tight variant wasn't justified. Switch to the default 20dp.
