Add ops & quality quick wins: health check, format gate, Dependabot, license

- /health endpoint backed by an EF Core DbContext check (verifies the DB).
- CI format gate: .editorconfig + `dotnet format --verify-no-changes`.
- Dependabot for NuGet + GitHub Actions (weekly).
- MIT LICENSE.
- README updated to reflect these as implemented (moved out of limitations).

Applying the format rules also normalized whitespace/braces in a few existing
files (cosmetic only; build + 27 tests + format gate all green).
