Critical Security Fixes 🔒

• 🛡️ Fixed 5 SQL injection vulnerabilities:

  1. Extension/Jlcontentfieldsfilter.php (3 vulnerabilities):

     • Line 235: BETWEEN clause - missing int cast for 'to' value

     • Line 244: LIKE clause - added db->escape() before db->quote()

  2. TagModel.php (line 170): IN clause - sanitized with ArrayHelper::toInteger() + array_filter()

  3. ContactModel (CategoryModel.php, line 270): IN clause - sanitized with ArrayHelper::toInteger() + array_filter()
