Add Progress over time and a targets and reminders setup

Progress gives a Day/Week/Month view of routines held against a weekly
target, compared with the same point of the previous period, with active
time and the daily streak. Targets & reminders sets routines and minutes
per week and schedules a heads-up before each routine. The runner's summary
now shows today's held count and streak. Finished runs are mirrored to a
device run log that feeds both.
