Refactor: Make FullScreenDialog dismissible

This commit introduces a dismiss functionality to the `FullScreenDialog`.

The `FullScreenDialog` now accepts an `onDismiss` lambda parameter.
This `onDismiss` lambda is invoked when a dismiss request is made for the dialog.

In `PhotoViewScreen`, the `onDismiss` lambda passed to `FullScreenDialog` is now the `onDismiss` lambda received by the `PhotoViewScreen` itself.
