[Automatic Import] CEL input auth configuration support

[ebeahan]

This is where we'd want to ensure all auth scenarios are supported. In the base phase, we don't add any auth to the program.

Requirements:

• [X] Updating UI to have user confirm endpoint and auth information
• [X] Reduce OpenAPI spec to minimally required information
• [ ] Update and add prompts to update the CEL program for auth (basic auth, oauth, api tokens)
• [ ] Update produced manifest files to include only selected auth information
• [ ] Update original program prompt for feedback from Dan mostly around error handling
