- Add special handling for `ImageBatchInvocation`
- Add input component for image collections, supporting multi-image upload and dnd
- Minor rework of some hooks for accessing node data
We don't need a "dnd" image system. We need a "image action" system. We need to execute specific flows with images from various "origins":
- internal dnd e.g. from gallery
- external dnd e.g. user drags an image file into the browser
- direct file upload e.g. user clicks an upload button
- some other internal app button e.g. a context menu
The actions are now generalized to better support these various use-cases.
