fix(touch): harden long-press for iOS (#199)

Long-press opens the message action sheet (#166), but on iOS the system
takes a long-press for itself: the link/image callout or the text-selection
loupe races the 450 ms press. Message rows on touch screens now carry
data-touch-actions (no -webkit-touch-callout), and the pressed row carries
data-pressing from touch-down until the finger lifts, which turns text
selection off for that moment only. Copy Text stays in the sheet.
