0.18.1: editor-hide cascades to groups + rename for layers & clip tracks

Track groups get the same editor-hide affordance as layer and clip
tracks: new eye button on the group header, setGroupEditorHidden
action (clears selection pointing inside the group), and a cascade
through the Konva stackItems + render.ts so every child track in a
hidden group vanishes in the editor.

Track renaming via right-click context menu now covers layers and
clip tracks too — setLayerName / setClipTrackName actions, new i18n
strings, and end-to-end UI tests driving the menu → promptDialog →
rename flow.
