fix(ui): query preset where field not displaying array values (#13961)

### What?

Query preset WhereField component was not displaying array values
correctly. When using relationship fields with operators like "is in"
that accept multiple values, the array values were not being formatted
and displayed properly in the query preset modal.

### Why?

The original `renderCondition` function only handled single values and
date objects, but did not include logic for arrays. This caused
relationship fields with multiple selected values to either not display
correctly or throw errors when viewed in query preset modals.

### How?

- Added proper array detection with `Array.isArray()` in the
`renderCondition` function
- Created a reusable `formatValue` helper function that handles single
values, objects (dates), and arrays consistently
- For arrays, format each value and join with commas:
`operatorValue.map(formatValue).join(', ')`
- Enhanced `addListFilter` test helper to accept both single values
(`string`) and arrays (`string[]`) for relationship field testing
