feat(ui): status/tag context menu + ThemedDatePicker in task row

Adds "Set status" and "Tags" submenus to the row context menu (tags
list is built lazily on Opening from AllTags ∪ row tags). Replaces
the schedule flyout's separate DATE / TIME pickers with a single
ThemedDatePicker in date+time mode.
