- saveAppSettings no longer sends webglRendererEnabled on the settings PUT:
the key is absent from the .strict() SettingsUpdateSchema, so every save
400'd with INVALID_INPUT, silently killing all server-side settings
persistence. Stripped in the per-device destructure alongside
localEchoEnabled/skin/etc.
- shouldSkipWebGL now treats a stored true like the untouched default w.r.t.
the sticky marker: the checkbox defaults checked on desktop, so any
unrelated save stored true and every page load then cleared the
'codeman-webgl-disabled' marker, permanently defeating the GPU-stall
auto-fallback. Only ?webgl=force clears the marker at init.
- The marker is instead retired on a real OFF->ON toggle flip detected at
save time (mirrors the _prevGestureEnabled pattern in settings-ui.js).
- webglRendererEnabled added to the displayKeys per-device set in
loadAppSettingsFromServer (renderer choice is device/GPU-specific; syncing
would leak mobile's hidden-checkbox false onto desktop).
- Tests: stored true + sticky marker -> still skips WebGL; OFF->ON save
clears the marker and keeps the key off the wire; default-checked save
leaves the marker alone; ?webgl=force / ?nowebgl behavior unchanged.
