fix(filter-control): wire up hideUnusedSelectOptions for hide-unused-select-options

[sawirricardo]

Description

The hideUnusedSelectOptions function in src/extensions/filter-control/utils.js was defined and exported but never called anywhere, making the data-hide-unused-select-options attribute completely non-functional.

Reported in #7719 — the feature last worked in v1.19.1.

Changes

• Add filterControlHideUnusedSelectOptions: false to the filter-control default options
• Call hideUnusedSelectOptions(selectControl, uniqueValues) in initFilterSelectControls when the option is enabled

Example

<table data-toggle="table"
       data-filter-control="true"
       data-filter-control-hide-unused-select-options="true"
       data-url="json/data1.json">
  <thead>
    <tr>
      <th data-field="id" data-filter-control="select">ID</th>
      <th data-field="name" data-filter-control="select">Name</th>
    </tr>
  </thead>
</table>

Fixes #7719
