Updated CMakePresets.json to add 'testnet' and 'mainnet' workflows, removed unused Windows preset, and improved environment and cache variable handling. Makefile targets for testnet and mainnet workflows were added, and Conan-related targets were renamed for consistency. Added a function to reset ConanPresets.json in CleanBuild.cmake and fixed the path for GetConan.cmake in conan_provider.cmake. Deleted obsolete .idea/cmake.xml.
