Four separate text_constants.inc.php files (root, mysyde/common,
mysyde/common/classes, mysyde/admin) contained overlapping and
diverging constants. Merged all 1596 unique keys—zero value conflicts—
into mysyde/admin/text_constants.inc.php, which Translate.php already
loads. The three other files are now thin stubs that require_once the
admin file, so all existing include paths continue to work.
