main ← fix/push-subscription-logout-per-device
merged 02:39PM - 15 Apr 26 UTC
## Summary
- Previously, logging out of any device cleared push notification su…bscriptions for **all** devices via a blanket `user_logged_out` event handler
- Now the frontend sends the current browser's push subscription as part of the session destroy request, and only that subscription is removed server-side
- "Log out everywhere" paths (admin log out, user suspension, `log_out_strict`) still correctly clear all subscriptions
