bug(racks-ui): small rack causes overflowing items

### Describe the bug

When creating a smaller rack (in this case 3x2), the miner states will overflow their table and look strange.

### Preconditions

Having a small created rack, such as 3x2.

### Steps to reproduce

1. Create a 3x2 rack,
2. Optionally add miners,
3. Go to the page for that rack,
4. To the right of the rack, the miner states will be squished and overflowing.

### Expected behavior

Ideally the rack image spacing should expand to ensure the min height for the states icons are met.

### Proto Fleet version

v0.2.7

### Environment

Browser: Firefox 151.0 (64-bit)

### Logs

```shell

```

### Screenshots & screen recordings

Start at the rack page and its rack/miner-state UI entry points, then reproduce the issue with a 3x2 rack in the browser. Inspect the layout around the rack image and miner states; done means the state icons remain readable and do not overflow or become squished on small racks.
