Fix app lock issue (#958)

* Fix app lock issue

Fixes #954

Add app lock feature when the app is not in the foreground.

* **Settings Fragment**
  - Add a new setting to specify the time duration after which the app will lock when not in the foreground.
  - Update the UI to include this new setting.

* **Dashboard Activity**
  - Implement logic to lock the app when it goes to the background.
  - Use the new setting to determine the time duration after which the app will lock.
  - Add handlers to manage the lock timeout when the app is paused and resumed.
