chore: Refactor vcpkg.json and update CMake configurations

- Removed the abseil dependency from vcpkg.json for Windows platform.
- Updated CMake configuration to prevent finding system-installed protobuf and abseil, ensuring gRPC uses bundled versions.
- Modified todo_manager.cc to convert paths to strings for consistency.
- Updated vision_action_refiner.cc to explicitly convert stripped whitespace strings to std::string.
- Added undefinitions for Windows macros in z3ed_network_client.cc to avoid conflicts with method names.
