CMM-676 DataView custom empty view

[nbradbury]

Closes CMM-676

Prior to this PR, when the list of items in a DataView was empty we would always show the empty view text for the Subscribers feature. This meant that when viewing application passwords, the user would be told "There are no subscribers" if the password list was empty.

Luckily, the password list should never be empty, but this still needed to be addressed. So this PR resolves this by using a default generic empty view which can be overriden.

Here's the default empty view:

And here's the empty view overriden for Subscribers:

Pull Request Overview

This PR introduces customizable empty views for the DataView component to replace the hardcoded Subscribers empty view that was incorrectly shown for all DataView implementations.

• Added a customizable DataViewEmptyView class with default generic empty state text and image
• Updated SubscribersViewModel to override the empty view with subscriber-specific content
• Modified DataView screen components to accept and use the custom empty view parameter
