📔 Objective

This pull request introduces a feature flag to control logout behavior when a push notification is received for a KDF (Key Derivation Function) change. If the new NoLogoutOnKdfChange flag is enabled, the app will avoid logging out the user when the logout reason is a KDF change.

Feature: Avoid logout on KDF change

• Added a new feature flag NoLogoutOnKdfChange to FlagKey, including its display label and debug menu integration, allowing toggling the behavior from the UI.
• Updated PushManagerImpl to check the new flag and skip emitting logout events if the logout reason is KDF_CHANGE in push notifications.
• Modified dependency injection to provide FeatureFlagManager to PushManagerImpl.
