tui(reader): flag bookmarked verses with a red * in the reading pane

A verse that has a bookmark now shows a red "*" at the end of its last line, so
saved verses are visible while reading. The set of bookmarked verses for the
current book+chapter is refreshed on chapter load, on save, and on returning
from the bookmarks list (one store read each). Test covers the flag + render.
