Fix Persian/RTL characters display in Ability Explorer schemas

[kabookhypnosis]

What?

Fixes the display of non‑ASCII characters (e.g., Persian, Arabic, Urdu) in the Ability Explorer schema viewer. Previously these characters were rendered as escaped unicode sequences such as \u0645\u062d\u062a\u0648\u0627.

Why?

When abilities include localized descriptions or examples in languages using non‑ASCII characters, the schema viewer becomes difficult to read because the JSON output escapes all Unicode characters. This reduces usability for multilingual environments and RTL languages.

How?

Adds the JSON_UNESCAPED_UNICODE flag to wp_json_encode() calls in:

includes/Experiments/Abilities_Explorer/Admin_Page.php

This ensures that schema data is rendered in a human‑readable format while preserving valid JSON output. Existing escaping (esc_html, esc_textarea) remains unchanged to maintain output safety.
