refactor(notifications): keep the push sender contract next to the fan-out

The payload, target and outcome types are shared by the Expo and web push senders, so they now
live with PushSender in push-notifications.ts instead of in the web push adapter. The settings
E2E also stubs the Notification permission (headless Chromium reports it as denied even when
granted), and the quiet-hours inputs are wide enough for 12-hour times.
