Read a flow name, a port name and an honest docstring

Give the Home flow-activity name cell a `sm:min-w-32` floor beside its
`max-w-0` cap, so an ordinary name reads in full where there is room
while the phone keeps today's truncation. Name the bar widget's nested
reading by its port rather than its qualified message. Correct
`MarkdownWidget`'s docstring to the subset it actually renders.
