Define interfaces over the three domain services that the view model hard-news
today (the testability blocker). Concrete types implement the new interfaces;
no wiring or behavior change yet.

Establishes a safety net before refactoring, and lands the first
behavior-preserving cleanup.
Tests (no production behavior change):
- SensorFormatter: full per-type coverage of GetFormatString, FormatValue,
and GetPlotUnit across every SensorType.
- RemoteWebServer: extract testable seams (ResolveRoute, VerifyCredentials,
internal pure helpers) and pin routing (incl. the no-hijack rule), query
and Prometheus parsing, JSON/metric shape, credential semantics, and the
legacy SHA-256 vector.
- HardwareMonitorService: pin the enable-flag -> settings-key mapping.
- Logger: add a TimeProvider/base-dir test seam; deterministic rotation tests.
- Add [InternalsVisibleTo] for the test project.
Cleanup:
- Collapse SensorFormatter's three parallel SensorType switches into one
GetFormat source of truth; dedupe CelsiusToFahrenheit. Verified identical
by the new characterization tests.
167 tests pass (was 55).
