Reduce clicks for file upload

I would like to propose adding two buttons to the Lakehouse file explorer in the web UI.

Currently, when you are inside a folder, there is no convenient way to create a new folder at that location or upload a file.

Two buttons at the top right of the explorer, “New folder” and “Upload file”, would make this much easier.

Additionally, it would be helpful to support dragging and dropping files directly into the selected folder.
