fix: enable case-insensitive array comparison in jsonLogic operators

[ousamabenyounes]

What does this PR do?

Fixes the ==, ===, !=, and !== operators in packages/lib/raqb/jsonLogic.ts to correctly compare arrays element-by-element instead of by JS reference equality.

Problem

JavaScript's == and === compare arrays by reference, so ["hello", "world"] === ["hello", "world"] is always false. This meant that multiselect "equals" comparisons in routing forms would never match, even when the selected values were identical.

A skipped test (should compare arrays case-insensitively) confirmed this bug.

Fix

Added an areEqual helper that:

1. Normalizes both operands (lowercases strings)
2. If both are arrays, compares length then each element
3. Falls back to strict equality for non-arrays

Tests

• Unskipped the existing it.skip test for array comparison on ==
• Added new array comparison tests for ===, !==, and !=
• All 23 tests pass (was 19 pass + 1 skip)

TZ=UTC yarn vitest run packages/lib/raqb/jsonLogic.test.ts

Mandatory Tasks (DO NOT REMOVE)

• I have self-reviewed the code (A decent size PR without self-review might be rejected).
• I have updated the developer docs in /docs if this PR makes changes that would require a documentation change. N/A.
• I confirm automated tests are in place that prove my fix is effective or that my feature works.

How should this be tested?

TZ=UTC yarn vitest run packages/lib/raqb/jsonLogic.test.ts

All 23 tests should pass, including the previously-skipped array comparison test.
