Upgrade to FastMCP 3.0, update get/set state to async

[pamelafox]

The only breaking change was the async get/set state, all other changes seem compatible.

Manual verification:

• The Entra MCP server works locally and in production
• The Keycloak MCP server works in production. Locally, it was going to localhost:8000/authorize and 404ing. Did this work before? It seems like it should hit up a different authorize URL.
