Closes https://github.com/enso-org/cloud-v2/issues/560
- New context menu
- Global keyboard shortcut handler
- Moves the existing "escape" keybindings (close modal, cancel editing names) to global keybind handlers
# Important Notes
- The "Upload To Cloud" action is not present in the Figma design. As such:
- Its current icon is an edit of the "cloud_from" icon, with the arrow upside down
- It does not have a corresponding keyboard shortcut
