Expose cloud event logging endpoint to GUI and render GUI editor as react component. (#9951)
fixes #9730

Added a `logEvent` method to remote backend implementation in dashboard. Added an always-present remote backend instance that can be used for logging even when running a local project (intentional behavior).

# Important Notes
Because the backend implementation requires access to always fresh session token, the logger needs to be periodically updated on GUI side, so it can continue to function. To accomplish that, I simplified the app loading logic to treat GUI as an ordinary react component, so its props can be updated with normal react rendering flow. That refactor also removed the dynamic GUI asset loading code that was only needed for Rust GUI.
