M0: scaffold solution, EF+Timescale schema, /healthz

Five-project Clean Architecture solution (Core/Infrastructure/App + Core.Tests/ Integration.Tests) on .NET 10 with central package management, snake_case EF mapping, and shared build/style config. - Full domain entity set + EF DbContext for the SDD §5.3 schema (singular table names). - InitialSchema migration (relational) + TimescaleHypertables migration (raw SQL: create_hypertable + compression on reading, hypertable on consumption). - App wiring: Serilog (actually wired, unlike MQTTower), DbContext, migrate-on-startup, /healthz. Serves plain HTTP behind a reverse proxy (no HTTPS redirect). - deploy/Dockerfile (2-stage, ICU-capable) + docker-compose (app + timescaledb). - Integration.Tests: shared TimescaleFixture (Testcontainers) — migrations, hypertables, compression policy, and /healthz all verified green (4/4).
