Title: fix visible_area recalculate for manual crop in reflow mode

Calling `self.ui:handleEvent(Event:new("SetZoomMode", "page"))` will have no effect because the original page mode is always page mode in reflow mode. In that case, we need to call ReaderView:recalculate to force update visible_area.
