Align: keep the tests and panel docs #1073's branch dropped, and translate the new button

The branch was cut from an older main, so its commit also removed four engine tests (stroke and
paint rejection, malformed anchor selection, bad anchors in path commands), the newer
window.panel.float/dock parameter docs and the un-collapse on showing a floating panel. This puts
them back and adds the Horizontal & Vertical Align Center label to the complete catalogs.
