The internal `BatchProcessStorage.get_session()` method throws when it finds nothing, but we were not catching any exceptions.
This caused a exception when the batch manager handles a `graph_execution_state_complete` event that did not originate from a batch.
Fixed by handling the exception.
If the values from the `session_dict` are invalid, the model instantiation will fail, or if we end up with an invalid `batch_id`, the app will not run. So I think just parsing the dict directly is equivalent.
Also the LSP analyser is pleased now - no red squigglies.
Providing a `default_factory` is enough for pydantic to know to create the attribute on instantiation if it's not already provided. We can then make make the typing just `str`.
Previously the editor was using prop-drilling node data and templates to get values deep into nodes. This ended up causing very noticeable performance degradation. For example, any text entry fields were super laggy.
Refactor the whole thing to use memoized selectors via hooks. The hooks are mostly very narrow, returning only the data needed.
Data objects are never passed down, only node id and field name - sometimes the field kind ('input' or 'output').
The end result is a *much* smoother node editor with very minimal rerenders.
There is a tricky mouse event interaction between chakra's `useOutsideClick()` hook (used by chakra `<Menu />`) and reactflow. The hook doesn't work when you click the main reactflow area.
To get around this, I've used a dirty hack, copy-pasting the simple context menu component we use, and extending it slightly to respond to a global `contextMenusClosed` redux action.
- also implement pessimistic updates for starring, only changing the images that were successfully updated by backend
- some autoformat changes crept in
