Use escapeTitle in pagination element

[dereuromark]

Using 'escape' => false on Paginator helpers also disables HTML escaping of attributes (URL, class, title attr), not just the title text. The narrower 'escapeTitle' => false keeps attribute escaping on while still allowing the icon markup in the title.

Affects templates/element/pagination.php only.

Before	After
['escape' => false]	['escapeTitle' => false]

Defense-in-depth — no known exploit path because the call sites pass static strings, but keeping the strict default protects against future edits that wire dynamic values into pagination options.
