List preferences were improperly saving their own records onto
themselves when building table state through the server function. This
was happening because the entire preference document was being spread
onto the new preferences, as opposed to just the value itself:
```diff
const mergedPrefs = {
- ...(preferencesResult || {}),
+ ...(preferencesResult?.value || {}),
columns,
}
```
This PR also swaps `dequal` out for `dequal/lite`.
