fix(dashboard): flatten header; replace greeting with date+time; split overdue/soon chips

Header shows current date and time instead of user name + separate date line.
urgentCount replaced by overdueCount (overdue tasks) and dueSoonCount (due today/soon),
each with a distinct chip color. formatDueDate updated to accept due_time and return
accurate overdue/soon states against the current moment.
dashboard grid expands to 4 columns at 1280px instead of 1440px.
