Add minimum sizing to images (incurring blurring if needed)

### Your use case

#### What would you like to do?

Images and other media in the timeline should have a minimum size of 32x32 or so to ensure the layout doesn't break.

#### Why would you like to do it?

If someone sends a 1x1 image, the message layout looks broken.

#### How would you like to achieve it?

`Math.max(dimension, 32)` or similar.

### Have you considered any alternatives?

### Additional context

_No response_

No file or test is named. Start by locating the timeline's image and other media rendering entry point, then reproduce the layout with a 1x1 image. Done means timeline media is rendered at least 32x32, with the expected blurring when an image must be enlarged.
