- Add PartyIndex field to protobuf ParticipantInfo message
- Pass original PartyIndex from account shares to session coordinator
- Use original PartyIndex instead of loop variable when creating participants
- This fixes TSS signing failures when non-consecutive parties are selected
- Add keygen_session_id field to CreateSessionRequest and SessionInfo protobuf
- Modify CreateSigningSessionAuto to accept and pass keygenSessionID
- Update Account Handler to pass account's keygen_session_id when creating signing session
- This enables parties to load the correct keyshare by session ID
- Add signing-config API endpoints (POST/PUT/DELETE/GET) for configuring
which parties should participate in signing operations
- Add SigningParties field to Account entity with database migration
- Modify CreateSigningSession to use configured parties if set,
otherwise use all active parties (backward compatible)
- Add delegate party signing support: user provides encrypted share
at sign time for delegate party to use
- Update protobuf definitions for DelegateUserShare in session events
- Add ShareTypeDelegate to support hybrid custody model
API endpoints:
- POST /accounts/:id/signing-config - Set signing parties (first time)
- PUT /accounts/:id/signing-config - Update signing parties
- DELETE /accounts/:id/signing-config - Clear config (use all parties)
- GET /accounts/:id/signing-config - Get current configuration

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).

- Add SessionCoordinatorClient gRPC adapter with connection retry logic
- Implement MPCHandler with real gRPC calls to session-coordinator
- Replace placeholder implementation with actual session creation
- Add keygen and signing session endpoints with proper validation
- Include comprehensive implementation summary documentation
This enables account-service to create real MPC sessions via gRPC
instead of returning mock data. Requires main.go integration to activate.
