feat(hanzo-iam): canonical IAM_ env contract + FastAPI integration (1.30.0)

Bumps hanzo-iam from 1.29.0 (older Casdoor SDK port) to 1.30.0 with a
purpose-built IAM SDK aligned to the canonical IAM_ env contract.

- ENV_PREFIX="IAM_" only — no HANZO_IAM_ / {ORG}_IAM_ fallback chain.
- IAMConfig.from_env reads IAM_ENDPOINT, IAM_CLIENT_ID, IAM_CLIENT_SECRET,
  IAM_ORG, IAM_APP, IAM_CERT, IAM_USERINFO_URL.
- New FastAPI middleware module wraps Casdoor sign-in flow with
  request-state user injection.
- 19 unit tests covering env-read, validation, and FastAPI integration.

Consumer packages (hanzo-cli, hanzo-tools-auth, hanzo-tools-paas) bump
their hanzo-iam dep to >=1.30.0.
