Family version-matrix alignment. No behaviour change — mxgw registers no Akka
checks, and 0.2.0's per-entry `data` object is emitted only when a check
publishes some, so its health payloads are byte-identical.
Note: this repo uses inline package pins, NOT central package management (there is
no Directory.Packages.props), so the version lives in the Server csproj.
Verified: Server builds 0 warnings.
Part of scadaproj docs/plans/2026-07-22-overview-dashboard-impl-plan.md Task 2.3.
