Pull request overview

This PR adjusts the CMake build so missing web-backend dependencies (mongoose source or OpenSSL for Boost.Beast) don’t break configuration unless the WEBServer module is actually being built, by conditionally skipping the nscp_mongoose library and related tests.

Changes:

• Add NSCP_MONGOOSE_AVAILABLE in dependencies.cmake and downgrade missing-backend handling from FATAL_ERROR to STATUS.
• Skip building libs/mongoose-cpp (and its wrapper tests) when backend dependencies are unavailable; emit a targeted FATAL_ERROR only when building the WEBServer module without nscp_mongoose.
• Remove unused ALL_LIB_NAMES accumulation from the top-level CMakeLists.txt.

I'm testing now and with -DBUILD_MODULE_WEBServer=OFF and -DNSCP_WEB_BACKEND=mongoose (default) don't build the webserver part but if in future will be -DNSCP_WEB_BACKEND=beast the default with boost and openssl installed will build even if -DBUILD_MODULE_WEBServer=OFF, or I'm wrong?
