Reminders: global repeat toggle + per-dose "Ikke forstyrr"

Two ways to stop the every-10-min nag, per feature request:

- A global "Gjenta påminnelser" switch in Settings. Off → a due dose
  alerts once and goes quiet; only the automatic re-nag chain is gated,
  so an explicit "Utsett 15 min" still gives one more reminder. The gate
  sits at the three automatic arm points (fireOccurrence, escalate
  re-arm, armAll resume-after-reboot), never on Snooze.

- An "Ikke forstyrr" action that appears from the second reminder on
  (nagCount >= 1). It stops nagging this one dose but leaves it PENDING
  so it can still be taken later — distinct from Skip. Implemented by
  jumping to the existing terminal state (nagCount = NAG_CAP) rather than
  a new column, so it needs no migration and survives reboot for free
  (armAll re-arms only nagCount < cap).
