- Fixed delegate party event handler to use parent context with timeout
- Fixed message acknowledgment to use parent context
- Prevents orphan goroutines when session fails or party exits
- Resolves system crash after delegate party failure
The JoinSession response contains OtherParties (excluding self) and
PartyIndex (self's index). The participants list passed to TSS keygen
must include all parties including self, otherwise validation fails
with "invalid party count" error.

- 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

- Add ShareForUser field to ParticipateKeygenOutput
- Implement role-based share handling (persistent/delegate/temporary)
- Add in-memory share cache with 15-minute TTL for delegate parties
- Add GET /api/v1/sessions/:session_id/user-share endpoint for one-time share retrieval
- Shares from delegate parties are NOT saved to database
- Add comprehensive Delegate Party implementation guide
This implements hybrid custody model similar to Fireblocks and ZenGo:
- Persistent parties: shares stored in server database
- Delegate parties: shares returned to user, deleted from memory after retrieval

- Added debug logging for party_index conversion in gRPC messages
- Removed redundant party filtering logic
- Added detailed logging to trace protobuf field values
