feat(11-04): add reminder picker to EventForm (allDay swap, edit pre-population, payload mapping)
- TIMED_REMINDER_PRESETS + ALLDAY_REMINDER_PRESETS sets for preset classification
- humanizeReminderLead() + deriveReminderValue() helpers for off-list synthetic options
- reminderValue state (__none__ / numeric string / __custom__ sentinels)
- allDay toggle resets reminderValue to __none__ (D-03 — no carry-over)
- Reset effect derives reminderValue from occurrence.reminderLeadMinutes on mount/cache update
- Reminder <select id=event-reminder> after Recurrence picker: allDay-conditional option swap (D-02), timed presets when !allDay, day-granularity presets when allDay; synthetic off-list option; Custom (kept) read-only disabled option
- Helper text under select in edit mode for off-list/custom states (D-07)
- executeSubmit payload: __none__ → null, numeric → integer, __custom__ → field omitted (D-08)
- 10 new Phase 11 reminder picker tests (create/allDay-swap/edit-pre-pop/payload-mapping); fix pre-existing None-ambiguity test
- pwa vitest 201/201 pass; tsc --noEmit clean
