Moved genesis-related generated files and logic from currency_core/generated and genesis_generator to a new src/genesis directory. Updated CMakeLists and include paths to reflect the new structure. Adjusted test and db build scripts to use ZLIB::ZLIB and miniupnpc::miniupnpc targets. Added README with instructions for genesis block updates. Removed premine wallet generation logic from config CMakeLists.
Moved currency_config.h and related CMake/config files to a new src/config directory, creating a dedicated config CMake target. Updated all includes and build scripts to reference the new config location. Removed obsolete cmake/ChainConfig.cmake and example currency config, and restructured genesis generator and premine wallet logic into the new config system for improved modularity and maintainability.
