1. Copy address button:
- Changed from alert() to visual feedback (shows "✓ 已复制")
- Feedback auto-hides after 2 seconds
2. Explorer link button:
- Was hardcoded to testnet (true)
- Now uses getCurrentNetwork() to determine correct explorer URL
- Links to kavascan.com for mainnet, testnet.kavascan.com for testnet

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

Previously Home.tsx hardcoded testnet RPC for balance queries.
Now uses getCurrentRpcUrl() to respect user's network setting.

- Changed getGasPrice() to use eth_gasPrice RPC method instead of calculating
from baseFeePerGas (which is for EIP-1559 transactions)
- Added 10% buffer to gas price to ensure transaction gets included
- Updated Home.tsx to use gasPrice instead of maxFeePerGas for display
KAVA doesn't support EIP-1559, so we must use Legacy (Type 0) transactions
with gasPrice from eth_gasPrice RPC.

KAVA EVM does not support EIP-1559 dynamic fee transactions.
Changed from EIP-1559 (Type 2) to Legacy (Type 0) format:
- prepareTransaction: Use [nonce, gasPrice, gasLimit, to, value, data, chainId, 0, 0]
- finalizeTransaction: Use EIP-155 v calculation (chainId * 2 + 35 + recoveryId)
- Remove type prefix (0x02) as Legacy transactions don't need it
- Update Home.tsx and CoSignSession.tsx to use gasPrice instead of maxFeePerGas

BigInt cannot be serialized by JSON.stringify. Convert gasLimit,
maxFeePerGas, maxPriorityFeePerGas, and value to strings before
storing in sessionStorage.
