feat: add Docker infrastructure for 8-node cluster topology (2 central + 3 sites)

Multi-stage Dockerfile with NuGet restore layer caching, per-node appsettings with Docker hostnames, shared bridge network with infra services, and build/deploy/teardown scripts. Ports use 90xx block to avoid conflicts.
