Major changes:
- Add complete Android app (service-party-android) with Jetpack Compose UI
- Implement real account-service API calls for keygen and sign sessions:
- POST /api/v1/co-managed/sessions (create keygen session)
- GET /api/v1/co-managed/sessions/by-invite-code/{code} (validate invite)
- POST /api/v1/co-managed/sessions/{id}/join (join keygen session)
- POST /api/v1/co-managed/sign (create sign session)
- GET /api/v1/co-managed/sign/by-invite-code/{code} (validate sign invite)
- POST /api/v1/co-managed/sign/{id}/join (join sign session)
- Add QR code generation and scanning for session invites
- Remove password requirement (use empty string)
- Add floating action button for wallet creation
- Add network type aware explorer links (mainnet/testnet)
Network configuration:
- Change default network to Kava mainnet for both Electron and Android apps
- Electron: main.ts, transaction.ts, Settings.tsx, Layout.tsx
- Android: Models.kt (NetworkType.MAINNET default)
Features:
- Full TSS keygen and sign protocol via gomobile bindings
- gRPC message routing for multi-party communication
- Cross-platform compatibility with service-party-app (Electron)

Root cause: After keygen/sign completion, the gRPC message stream was not
unsubscribed. On the second operation, prepareForSign/prepareForKeygen
would try to cancel the stale stream, causing "CANCELLED: Cancelled on client".
Changes in tss-handler.ts:
- Add grpcClient.unsubscribeMessages() in all cleanup paths:
- participateKeygen close handler
- participateKeygen error handler
- participateSign close handler
- participateSign error handler
- cancel() method
- Reset sessionId and partyId in all cleanup paths
Changes in main.ts:
- Add reconnection logic in app 'activate' event for macOS

The app was crashing with "CANCELLED: Cancelled on client" error when
opening the app a second time. This happened because:
1. When window was reopened, old gRPC streams were in cancelled state
2. prepareForSign/prepareForKeygen tried to subscribe on cancelled streams
3. The error was unhandled and crashed the app
Changes:
- Add isConnected() check in prepareForSign() and prepareForKeygen()
- Throw meaningful error when gRPC client is not connected
- Wrap all prepareFor* calls in try-catch in main.ts
- Return user-friendly error message instead of crashing

Reverts e81757ad - the threshold conversion was wrong.
Keygen works with original thresholdT/thresholdN parameters.
The signing issue needs a different fix.

- Rename thresholdT/thresholdN to requiredSigners/totalParties in Create.tsx
- Add parameter conversion in main.ts: threshold_t = requiredSigners - 1
- In tss-lib, threshold t means t+1 parties needed to sign
- For 3-of-5: requiredSigners=3 → threshold_t=2 (t+1=3 signers)
- externalCount = requiredSigners (user parties)
- persistentCount = totalParties - requiredSigners (server parties)
- Backward compatible with legacy thresholdT/thresholdN format
BREAKING: Existing co-managed wallets need re-keygen with new params

Problem: Participants joining early only got incomplete participant list
from other_parties (only those who had joined), causing partyIndex mismatch.
Solution:
- Add parties field to SessionInfo (from validateInviteCode response)
- Pass parties to joinSession call from frontend
- Backend joinSession uses params.parties (complete list) instead of
result.other_parties (incomplete list)
- Add debug logging to track participant list state
Now all participants have the complete parties list with correct partyIndex.

- Add logic in handleCoSignStart to update participants from event.selectedParties
- Fix initiator immediate trigger to use other_parties + self instead of incomplete participants list
- Add debug logging for participant list updates
- Ensures all parties have correct participant list before TSS signing starts

The validateSigningSession handler was using parties.length for threshold.n
which returned 0 when parties array was empty. Now correctly uses the
threshold_n value returned from the backend API.

Add complete co-sign functionality for multi-party transaction signing:
Frontend (React):
- CoSignCreate.tsx: Create signing session with share selection
- CoSignJoin.tsx: Join signing session via invite code
- CoSignSession.tsx: Monitor signing progress and results
- Add routes in App.tsx for new pages
Backend (Electron):
- main.ts: Add IPC handlers for co-sign operations
- tss-handler.ts: Add participateSign() for TSS signing
- preload.ts: Expose cosign API to renderer
- account-client.ts: Add sign session API types
TSS Party (Go):
- main.go: Implement 'sign' command for GG20 signing protocol
- integration_test.go: Add comprehensive tests for signing flow
Infrastructure:
- docker-compose.windows.yml: Expose gRPC port 50051
This is a pure additive change that does not affect existing
persistent role keygen/sign functionality.
