debug: add logging for participant information in gRPC handlers

Added debug logging to track participant details including party_index in:
- account service MPC keygen handler
- session coordinator gRPC client
- session coordinator gRPC handler

This helps debug the party index assignment issue where all parties
were receiving index 0 instead of unique indices (0, 1, 2).
