Handle duplicate file uploads elegantly

[FSM1]

Is your feature request related to a problem? Please describe. Currently duplicate file uploads are not handled very well. The API will respond with a 409 error, and a notification will be displayed, but no further action will be presented to the user.

Describe the solution you'd like If a file with the same name already exists, a pop-up should be displayed to the user to allow them to either

• Rename the newly uploaded file
• Overwrite the existing file
