fix: add Guid to string conversion in gRPC source generator
The MapToProtoModel function was silently failing when mapping Guid properties to proto string fields, causing IDs to be empty in gRPC responses. Added explicit Guid → string conversion handling. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
