Room List: Tap Room avatar to open larger view

### Your use case

#### What would you like to do?
View a Room avatar in a larger format directly from the Room list.
#### Why would you like to do it?
The current flow requires three taps to view a Room avatar in full size, with two of those interactions located at or near the top of the screen. This increases interaction cost and makes the process less convenient, particularly on larger devices. Providing quicker access to the avatar would improve discoverability and reduce unnecessary navigation.
#### How would you like to achieve it?
Allow users to tap a Room avatar directly from the Room list to open the avatar in a full-screen image viewer/modal.

### Have you considered any alternatives?

Allow users to tap a Room avatar directly from the Room list to open a bottom sheet containing a larger preview of the Room avatar.

### Additional context
The Room name sits on top the image to prevent any obstruction.
- For that reason a stronger blur or shadow effect may be used around the name to ease readability.
