feat: notifications on Android while closed, with nothing to install

The phone fetches what is new every fifteen minutes with a poll secret
(POST /v1/push/poll) that reads notification lines and nothing else. When a
UnifiedPush distributor is already installed, the hub also pushes at once,
encrypted to the phone (RFC 8291); losing the distributor falls back to
fetching.

The hub now honours "disable all notifications" itself: create_notification
creates nothing for that account, as it already did for a muted group, so
neither switch lets anything reach a phone. The interface used to be the only
reader of the account-wide switch.

Push endpoints are member-supplied URLs: a send refuses non-public
addresses, connects to the address it checked, and follows no redirect.

Android build untested here (no SDK on this machine).
