Make the TLS streaming channel optional at configure time (DAQMODULES_LT_STREAMING_ENABLE_TLS)

[viacheslauK]

Summary

Adds DAQMODULES_LT_STREAMING_ENABLE_TLS (default ON) so the LT streaming modules can be built without the daq.lts:// / wss:// channel and its OpenSSL dependency. Behaviour is unchanged with the option on.

Changes

• New CMake option, forwarded to ws-streaming as WS_STREAMING_ENABLE_TLS and published as a
  compile definition;
• All TLS-specific code compiles out when the option is off — secure type/config factories, WSS server properties and listener, daq.lts discovery and capability, SSL error handling. A wss:// connection string then throws InvalidParameterException. A #error in common.h catches a mismatch with how ws-streaming was built.
• Client module gains helpers for the secure/plain choice, plus isSupportedServiceName() so discovery skips unsupported services instead of throwing.
• Tests: fixtures moved into headers, TLS-only cases split into *_module_tls.cpp built only with the option on.
