a11y: SettingTile labels its switch/select with the tile title (#185)

Every settings toggle was an icon-only role=switch with no accessible
name (36 axe 'button-name' criticals in User Settings, 3 in Room
Settings). SettingTile now gives the title an id and points any unlabelled
switch/input/select in its 'after' slot at it via aria-labelledby.
