/**
|
||
* Quiet-hours suppression for partner-action pushes.
|
||
*
|
||
* The Settings UI promises "10 PM – 8 AM, no notifications". The client stores the window in local
|
||
* DataStore AND mirrors it to the recipient's `users/{uid}` doc (quietHoursEnabled / *StartMinutes /
|
||
* *EndMinutes / timezone). Because a partner push carries a `notification` block, the OS shows it
|
||
* directly when the recipient app is backgrounded/killed — so the only place the promise can be kept
|
||
* is server-side, here, before the push is sent (M-001).
|
||
*
|
||
* FAIL-OPEN by design: if quiet hours is not explicitly enabled, or any field (window/timezone) is
|
||
* missing or malformed, we return `false` (do NOT suppress). A bug here can therefore only ever fall
|
||
* back to today's behavior (notification delivered) — it can never wrongly drop a notification, and
|
||
* existing installs keep delivering exactly as before until the client backfills the fields.
