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.

+- A Day / Week / Month switch over one white card: routines held against
+  the target, a change chip measured against the *same point* of the
+  previous period, and bars (days of the week, weeks of the month) with the
+  current one in night and future ones as stubs. Day shows a meter instead.
+- Two tiles below: active time against its target, and the daily streak.
+- Runs come from the device's run log (`RoutineRunRecord`), written when the
+  routine runner logs. Targets are local (`ProgressTargets`).
+- **Targets** (`TargetSetup`) is the only setup screen: routines per week,
+  active minutes per week and reminders before scheduled routines. Until it
+  is saved once, Progress measures against the schedule and shows a night
+  "Set your weekly target" prompt. Targets never touch debt.
