feat: add storage-service container with pluggable backends (Phase 1)

New FastAPI microservice (port 8020) providing unified blob storage via
PUT/GET/DELETE/LIST HTTP API. Local filesystem backend is the default (zero
extra deps). S3-compatible and WebDAV backends are built in. Backend is
switchable at runtime via POST /migrate, which copies all objects to the new
backend, verifies each one, atomically switches, then cleans up the old backend.

WebDAV XML parsing uses defusedxml to prevent XXE attacks.

Wired into docker-compose (storage_data volume) and registered in the backend
service-health poller as 'storage-service'.
