feat: per-section reminder edit, activity tab, more tests

Per-section reminder editing
- Replace the wizard-redirect edit shell with four focused single-form
  pages: /reminders/[id]/edit/{account,message,when,groups}.
- Each click on a section card on the detail page goes straight to the
  matching focused editor — no stepper, no other sections, no
  wizard chrome. Save returns to the detail page.
- New form components live under components/reminder-edit/:
  EditMessageForm, EditWhenForm (full recurrence builder reused),
  EditGroupsForm, EditAccountForm. All submit via updateReminderAction
  with the existing values for untouched fields. Switching account
  clears group targets (groups are scoped per account; the form warns
  and the user re-picks groups afterwards).

Activity tab
- New "Activity" item in the bottom nav + sidebar (between Reminders
  and Settings).
- /activity page: full run history (last 200), filter tabs (All /
  Success / Partial / Failed / Skipped), clickable rows that open the
  underlying reminder, and a Clear history dialog. Mirrors the
  dashboard's Recent Activity widget but with deeper data and its own
  empty-state messaging.

Tests (+20 — 80 passing total)
- qr-dedupe.test.ts: 14 tests covering the makeQrDedupe factory (per-
  account, fresh QRs always emit, reset/scope) and countdownRender
  (the QR-expired timer logic — danger threshold, expired flag,
  clamping). The dedupe + countdown logic is now used by pair-handler
  and pair-live.
- reminder-edit/edit-message-form.test.tsx: 6 tests verifying the form
  pre-fills, hides/shows the caption based on attachment, renders the
  Save (not "Schedule reminder") action, and the action receives the
  expected payload shape for both text-only and media-attached paths.
