This is a set of split off changes made as a side effect while working on engine reconnection handling.
Cleaned up GUI e2e setup, unified as much of the entrypoint code as possible. Currently the only real difference between the real and testing entrypoint is mocking of all network calls and not loading through dashboard.
I've managed to completely get rid of `MockApp`, and remove tricky mocking of pinia stores.
- Improved performance by batching simulatenous node edits, including metadata updates when dragging many selected nodes together.
- Updated Vue to new version, allowing us to use `defineModel`.
- Fixed#9161
- Unified all handling of auto-blur by making `useAutoBlur` cheap to register - all logic goes through a single window event handler.
- Combined all `ResizeObserver`s into one.
- Fixed the behaviour of repeated toast messages. Now only the latest compilation status is visible at any given time, and the errors disappear once compilation passes.
- Actually fixed broken interaction of node and visualization widths. There no longer is a style feedback loop and the visible node backdrop width no longer jumps or randomly fails to update.
