## Summary
- Fixes SaveWebM node showing "Error loading image" in Vue nodes mode
- Extracts `isAnimatedOutput`/`isVideoOutput` utility functions from
inline logic in `unsafeUpdatePreviews` so both the litegraph canvas
renderer and Vue nodes renderer can detect video output directly from
execution data
- Uses output-based detection in `imagePreviewStore.isImageOutputs` to
avoid applying image preview format conversion to video files
## Background
In Vue nodes mode, `nodeMedia` relied on `node.previewMediaType` to
determine if output is video. This property is only set via
`onDrawBackground` → `unsafeUpdatePreviews` in the litegraph canvas
path, which doesn't run in Vue nodes mode. This caused webm output to
render via `<img>` instead of `<video>`.

## Summary
Added `canvasOnly` flag to runtime-generated widgets to prevent Vue
renderer from displaying them while keeping canvas functionality intact.
## Changes
- **What**: Added `canvasOnly` widget option to hide upload, webcam, and
refresh widgets from Vue renderer
In the Canvas (LiteGraph) system, there was a small set of widgets with
strictly defined components. There, if we wanted some unique or
relatively complex behavior (like an upload butotn), we needed to create
a separate widget that would be coupled to the original widget at
runtime (and would not be serialized).
In the Vue renderer system, we can simply add flags to the inputSpec or
widget options and conditionally render complex UI additions -- i.e.,
there is no need for the hard-to-maintain runtime widget associations.
Expressing such things entirely in the view layer simplifies business
logic related to graph state, as we no longer need to account for
preserving the connections between runtime widgets and their special
siblings -- we also do not need to worry about the implications for
state serialization.
