New deployment-wide options bound from the "OpcUa" section of appsettings.json: - ApplicationName (default "ScadaLink-DCL") - TrustedIssuerStorePath / TrustedPeerStorePath / RejectedCertificateStorePath Empty paths fall back to Path.GetTempPath()/ScadaLink/pki/* so dev runs work without explicit config — same defaults the hardcoded values previously used. Wiring: - ServiceCollectionExtensions binds OpcUaGlobalOptions to the OpcUa section. - DataConnectionFactory takes IOptions<OpcUaGlobalOptions> and constructs RealOpcUaClientFactory with the snapshot. - RealOpcUaClient(globalOptions) replaces the hardcoded ApplicationName and the three CertificateTrustList store paths in ApplicationConfiguration. - Parameterless ctors on factory and client preserved for the existing test suite (32/32 DCL tests still green).
