WalletsScreen changes:
- Simplify onTransfer callback to only pass shareId
- Remove TransferDialog - now navigates directly to TransferScreen
- Remove unused state variables (showTransferDialog, transferWallet)
Bug fix:
- Remove 0x prefix from message_hash before sending to API
- Backend expects pure hex, not 0x-prefixed hex string

- Add warning log when parties miss session event broadcast (message-router)
- Add logging for subscribeSessionEvents to detect null asyncStub
- Add sessionStatusPollingJob field for future fallback polling mechanism
This helps diagnose why Android parties are not receiving session_started events.

Problem:
- Android initiator/joiner could miss session_started events due to race condition
- Events arriving between joinSession() and _currentSession.value assignment were ignored
- This caused keygen timeout because parties never started the TSS protocol
Solution:
- Add pendingSessionId field set BEFORE joinSession() call
- Modify startSessionEventSubscription() to match events against both activeSession and pendingSessionId
- Clear pendingSessionId on session completion, failure, or cancellation
This ensures session_started events are correctly processed even if they arrive
before _currentSession is fully initialized.

- Add getPartyId() method to TssRepository
- Call getSessionStatus after createKeygenSession to fetch all participants
including server-party-co-managed that have already auto-joined

Backend changes (session-coordinator):
- Add PublishParticipantJoined method to JoinSessionMessageRouterClient interface
- Implement PublishParticipantJoined in MessageRouterClient to broadcast events
- Call PublishParticipantJoined in join_session.go after participant joins
- Add detailed logging for debugging event broadcast
Android changes (service-party-android):
- Add detailed logging in TssRepository for session event handling
- Add detailed logging in MainViewModel for participant_joined processing
- Log activeSession state, event matching, and participant updates
This enables the initiator's waiting screen to receive real-time updates
when participants join the session, matching the expected behavior.

Removed polling fallback and simplified to match Electron's design:
- If joinSession returns sessionStatus="in_progress", trigger keygen immediately
- Otherwise wait for session_started gRPC event
Added debug log to show sessionStatus value for troubleshooting.

Changed from single 2-second delay to 5 attempts at 500ms intervals.
This provides faster detection while covering a longer window (2.5 seconds total).
The polling loop:
- Checks every 500ms for up to 5 times
- Stops immediately if keygen is already triggered
- Stops if session context changes (user cancelled/navigated away)
This handles the case where the last joiner triggers session_started
but cannot receive the event themselves.

When multiple Android devices join a keygen session nearly simultaneously,
the last joiner may miss the session_started gRPC event because it's sent
before the device has fully set up its event subscription.
This fix adds a 2-second delayed polling check after join to detect if
the session has already started. If the session is in_progress and we
haven't started keygen yet, trigger it via polling instead of relying
solely on the session_started event.

The server validates device_type and only accepts specific values.
Electron doesn't send device_info at all, which passes validation.
Match that behavior for consistency.

The app was crashing with FRAME_SIZE_ERROR because the gRPC client
was using plaintext mode when connecting to port 443 (TLS endpoint).
This caused the client to receive encrypted data that it couldn't parse.
Fix: Use useTransportSecurity() for port 443, usePlaintext() for other ports.

Both Electron and Android apps now calculate the maximum transferable
amount by subtracting estimated gas fees from the balance:
Electron (Home.tsx):
- Added calculateMaxAmount() async function that fetches gas price
- Uses 21000 gas limit for simple transfers
- Shows loading state while calculating
Android (TransferScreen.kt):
- Added calculateMaxTransferAmount() in TransactionUtils
- Uses coroutine to fetch gas price asynchronously
- Shows "..." while calculating, falls back to balance on error
Both implementations:
- Add 10% buffer to gas price for safety
- Round down to 6 decimal places
- Show error if balance insufficient for gas
