Fix "Copy entire row as JSON" button TypeError on non-string values (#2116)
## Summary

Fixes an operator-precedence bug in the "Copy entire row as JSON" button on the Search page. The `typeof value === 'string'` guard only applied to `value.startsWith('{')` but not `value.startsWith('[')`, so when a row contained a non-string value (number, boolean, etc.) the second `startsWith` call threw:

```
TypeError: s.startsWith is not a function
```

The fix moves the `typeof` check to guard both `startsWith` calls:

```diff
- (typeof value === 'string' && value.startsWith('{')) ||
- value.startsWith('[')
+ typeof value === 'string' &&
+ (value.startsWith('{') || value.startsWith('['))
```

### How to test locally or on Vercel

1. Open any Search page with results containing non-string column values (e.g. numeric or boolean fields).
2. Hover over a row and click the "Copy entire row as JSON" button (copy icon).
3. Verify the row is copied as valid JSON to the clipboard without a console error.
