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).
