implemented an E2E-encrypted Nextcloud push-v2 notification system with support for RSA decryption and signature verification; introduced an iOS Notification Service Extension and native AppDelegate handlers for Talk actions (inline reply and mark-as-read); replaced the legacy notification registration with a new lifecycle managing app passwords and secure keypair storage; added background message handling with tray synchronization and a test notification utility in the settings.
