feat: Complete Phase 2 Session & Service Management messages in C
Implemented comprehensive support for ISO 15118-2 Phase 2 messages: - SessionSetupReq/Res with EVCCID and EVSEID parsing - ServiceDiscoveryReq/Res with payment options and charge services - AuthorizationReq/Res with ID and challenge handling - ChargeParameterDiscoveryReq/Res with DC parameters and schedules Added 8 detailed helper functions with emoji indicators for improved readability and comprehensive parameter parsing including physical values, status codes, and complex nested structures. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
