Pull Request for Issue #46178

Summary of Changes

• Added support for the data-fuse-threshold attribute in <select> elements used by joomla-field-fancy-select.
• This allows the fuseOptions.threshold parameter of Choices.js to be configurable instead of fixed at 0.3.
• Default remains 0.3 for backward compatibility.

Testing Instructions

1. Create a form XML field definition with layout="joomla.form.field.list-fancy-select".
2. Add the new attribute data-fuse-threshold="0.1" to the <field> element.
3. Load the form in the Joomla backend and try searching in the select box.
4. Compare the fuzzy search sensitivity with and without the data-fuse-threshold attribute.
5. Verify that when no attribute is set, the behavior falls back to the default 0.3.

Actual result BEFORE applying this Pull Request

• fuseOptions.threshold was hardcoded to 0.3 and could not be adjusted.

Expected result AFTER applying this Pull Request

• Developers can set a custom fuseOptions.threshold value via data-fuse-threshold.
• If the attribute is missing, it falls back to 0.3.
