release: cut v1.4.0 — reminder notifications

Version bumped to 1.4.0 / 12. No code changes beyond the version — 1.4.0 is
the reviewed-and-approved reminder slice: the EVENT_REMINDER receiver posting
due CalendarAlerts on a dedicated channel, tap-to-detail, the one-time
onboarding step requesting POST_NOTIFICATIONS with the duplicate-reminders
warning, and the Settings mirror. CHANGELOG [1.4.0] carries the details.
