docs(health): align shared-contract to shipped API + per-lib CLAUDE.md + cleanup
- Contract: DatabaseHealthCheck<TContext> ctor now shows IServiceProvider (resolves
IDbContextFactory<TContext> when registered, else a scoped TContext; pool-safe)
- Contract: RequireActiveNode gains retryAfterSeconds = 5 default parameter
- Packages: remove dangling AspNetCore.HealthChecks.UI.Client PackageVersion (no
csproj referenced it)
- Tests: fix CS8625 in RoleLessCases — use object?[] so null role rows compile
warning-free under Nullable=enable
- Add ZB.MOM.WW.Health/CLAUDE.md (packages, responsibilities, consumer matrix,
build/test/pack commands, status + pointer to components/health/)
