[BUG]Unable to Save API Keys as environment variable when running in local server

[csaikarthikreddy-create]

Describe the bug
When running SIM in the local environment and trying to use the Copilot for developing the workflow, we are faced with an error. Although the API key was created in the cloud SIM environment we are unable to save the API key as an enviroment variable in the settings folder. The "Save" option does not function as intended. When we move to a different option the API key saved is lost.

To Reproduce
Steps to reproduce the behavior:

1. Run the npx simstudio or use docker compose
2. Open in the UI browser
3. Create an API key for the copilot on the sim.ai web app.
4. Go to settings in the local server running at localhost:3000
5. Click on Environment->Add->Save
6. Now move to another tab such as tools. Move back to the enviroment and the API key is missing

Expected behavior
API Keys are not saving while using local server.

Screenshots

After moving to a different setting option and returning back to the environment option

@csaikarthikreddy-create you don't have the ENCRYPTION_KEY set in your .env

Hey thanks for responding. I tried adding API keys and saving them. But they dont get added while running the server in the local. The same worked in the cloud environment. Regards, Sai Karthik

@csaikarthikreddy-create in the docker container thats running, you need to set ENCRYPTION_KEY set in your .env

you can see this line here: https://github.com/simstudioai/sim/blob/main/apps/sim/.env.example#L18
