[TASK] DatabaseRecordList: Streamline `fieldArray`

The `fieldArray` related configuration has been moved to the `getTable`
method.
The configuration handling for the `fieldArray` has been changed, in
order to avoid later unset on the `fieldArray`.

The `fieldArray` is only in the `getTable` and subordinated render
methods.
Therefore, the implicit configuration transfer like `fieldArray[0]`
for the label column has been replaced.
