fix(ui): receipt pill, insights counts, settings dividers, decoration preview (#269-#273)

#269 read-receipt pill sits at the message row's right edge, not where
     the text ends (outside the shrink-to-fit content column; grows in
     Compact). Bubble layout unchanged.
#270 Most Active Members: the bar's % is of its own track, so every row
     shows its count.
#271 Noise Suppression description at T200 like the rest.
#272 decoration preview shows your own avatar under the decoration; the
     empty state is a visible dashed circle.
#273 grouped settings get a divider between tiles (SettingTileGroup, via
     globalStyle; SettingTile roots carry data-setting-tile), and on phones
     the Sync tile's buttons sit under its description.
