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.

Changes:
- Change address derivation from deriveKavaAddress to deriveEvmAddress
in TssRepository.kt (3 locations)
- Add AddressUtils.isEvmAddress() and getEvmAddress() helper methods
to handle both old Cosmos and new EVM address formats
- Fix balance query for old wallets by deriving EVM address from
public key when needed (MainViewModel.fetchBalanceForShare)
- Add retry logic for optimistic lock conflicts in join_session.go
to prevent party_index collision during concurrent joins

Major improvements to Android gRPC client:
- Add automatic reconnection with exponential backoff (1s to 30s)
- Add heartbeat mechanism with failure detection (30s interval, 3 failures trigger reconnect)
- Add stream version tracking to filter stale callbacks
- Add channel state monitoring (every 5s)
- Add per-call deadline instead of one-time deadline for stubs
- Add SharedFlow for connection events (Connected, Disconnected, Reconnecting, Reconnected, PendingMessages)
- Add callback exception handling for robustness
- Add stream recovery after reconnection via callback mechanism
TssRepository changes:
- Save message routing params for recovery after reconnect
- Expose grpcConnectionEvents SharedFlow for UI notifications
- Auto-restore event subscriptions after reconnection
Other changes:
- Add QR code to Electron Create page for mobile scanning
- Auto version increment from version.properties
- SettingsScreen shows BuildConfig version info
- CreateWalletScreen tracks hasEnteredSession state

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.

Matching Electron app functionality:
1. Copy address button:
- Shows "✓ 已复制" feedback after copying
- Auto-resets after 2 seconds
2. Explorer link button (new):
- Opens address in Kava block explorer
- Uses correct URL based on network type:
- Mainnet: kavascan.com
- Testnet: testnet.kavascan.com
Changes:
- WalletsScreen: Added networkType parameter
- WalletDetailDialog: Added copy feedback state and explorer button
- MainActivity: Pass networkType to WalletsScreen

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
