Transfer Screen improvements:
- Add QR code scanning for recipient address (using zxing library)
- Support EIP-681 URI format (ethereum:0x...) and plain address

- Remove unused onScanQrCode callback parameter
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

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.

Backend changes (session-coordinator):
- Add PublishParticipantJoined method to JoinSessionMessageRouterClient interface
- Implement PublishParticipantJoined in MessageRouterClient to broadcast events

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

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 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.

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

When tsslib.aar is not found, the build script now automatically:
1. Checks if Go is installed
2. Installs gomobile if not present (go install golang.org/x/mobile/cmd/gomobile@latest)
3. Initializes gomobile if needed
4. Runs go mod tidy in the tsslib directory
5. Builds tsslib.aar using gomobile bind
This allows building APKs on any machine with Go installed, without
needing to manually compile the TSS library first.
Requirements:
- Go installed and in PATH
- Android NDK (installed via Android SDK)
