Fix OPC UA adapter: pass connection details, certificate stores, endpoint discovery

- DataConnectionActor now stores and passes connection details to adapter ConnectAsync
- DataConnectionManagerActor passes connection details when creating actor
- RealOpcUaClient uses DiscoveryClient for endpoint selection with no-security preference
- Added certificate trust store paths to prevent TrustedIssuerCertificates error
- Sanitize connection names for Akka actor paths (replace spaces)
