* Bulk rename "ComfyUI-TurntableGSViewer" -> "ComfyUI-GSViewer" across
package metadata, route prefix (/turntablegsviewer/spz ->
/gsviewer/spz), logger name, extension id, and all console-log tags.
* Extend onConfigure to defend against stale workflow schemas: rescues
stranded camera-state JSON into properties["Camera Config"] and
resets combo widgets whose value isn't in the option list. Fixes the
validator-reject when an old-schema basic.json (camera state glued
into widgets_values[3]) is loaded against today's renderer combo.
