[feature] Leverage gemini to auto-label tomes based on tome and params

Is your feature request related to a problem? Please describe.
Users don't give tomes labels making it hard to review activity

Describe the solution you'd like
Use gemini to write a short quest name instead of default generated tomes

• Add an environment variable and TF var to enable AI features. This should control all AI features in Realm.
• Grant tavern access to the tennants Gemini:
  • Ideally using IAM permissions and terraform bindings
  • Worst case pass Gemini API key to the server through environment variables.
• Add a backend API endpoint for AI this may need to be a new route in app.go with a new Endpoint specific to AI. This should require Tavern auth.
• Create an API for tome name generation. This should take-in:
  • Tome
  • Tome parameters
  • Beacon's being tasked (specifics like OS, group, or service may be especially useful)
• Prompt gemini to write a short quest name
• Modify the create quest flow to call this new API.
• If the API is slow ensure the name field displays a loading indicator but still allows a user to enter their own or use the randomly generated name. Consult with @cmp5987 before starting this part.
