What

Add snake_case config wrappers to the 4 PascalCase overlay ports (logger, container, database, network) so that all 8 ecosystem ports use a consistent find_package() convention.

Part of #532

Why

Consumers must currently guess whether to call find_package(common_system) or find_package(LoggerSystem). Standardizing to snake_case aligns with vcpkg port naming and the monitoring_system main CMakeLists.txt.

How

Port Changes (4 ports)

For each PascalCase port:

1. Change PACKAGE_NAME to snake_case in vcpkg_cmake_config_fixup
2. Create <snake_case>-config.cmake wrapper that includes the original PascalCase config
3. Create <snake_case>-config-version.cmake wrapper if version file exists
4. Bump port-version

Consumer Updates

• Update integration_tests/vcpkg_consumer/CMakeLists.txt to use snake_case find_package() names
• Update fix-vcpkg-dependency-discovery.patch (pacs) to use snake_case names
• Update vcpkg_replace_string path in network portfile

Acceptance Criteria

• find_package(logger_system) works (was LoggerSystem)
• find_package(container_system) works (was ContainerSystem)
• find_package(database_system) works (was DatabaseSystem)
• find_package(network_system) works (was NetworkSystem)
• vcpkg_consumer integration test updated
• No regression in CI
