Fix state mutation serverless action

[Devessier]

In this PR:

• Ensure the setNestedValue does a deep copy of the provided object and doesn't mutate it directly.
• Store the form's state in a useState instead of relying entirely on the backend's state. This makes the form more resilient to slow network connections.
• Ensure the input settings are reset when selecting another function.
• The Inner component now expects the serverless functions data to be resolved before being mounted, so I split it.
