Document sort input validation and recommend Sort::only()

[samdark]

Sort::any() accepts unconfigured field names, but the sorting guide could imply that its configuration limits the allowed fields. Recommend Sort::only() by default, show its use with user input, and explain that applications must validate untrusted field names when using Sort::any() to avoid SQL injection with database-backed readers.

Update the English and Portuguese guides, API comments, and changelog.
