Issue Title

bug: hash submission fails with 'key not found' when dest Terra wallet has no LUNC

Environment

Device Type: Desktop
Device Model: N/A
OS Version: Linux
Browser Version: N/A (reported via production use)
Wallet Used: Station (Terra) + MetaMask (EVM) — exact versions unknown
Network / Chain: BSC Mainnet → Terra Classic Mainnet
Page: Transfer Status (/transfer/:xchainHashId)

Steps to Reproduce

Connect an EVM wallet (MetaMask) on BSC and a new Terra Classic wallet that has zero LUNC balance (account never funded)
Initiate a bridge transfer of TestA token from BSC to Terra Classic
Deposit completes on BSC; navigate to the Transfer Status page
Wait for or click "RETRY SUBMIT" to submit the withdrawal hash on Terra Classic

Expected Behavior

The withdrawal submission should either succeed or display a clear, actionable error message explaining that the destination Terra wallet needs LUNC for gas fees

Actual Behavior

Hash submission fails with the error:

Transaction failed: rpc error: code = NotFound desc = account terra1leq08z2calpup577jpmxq82yvr8hx924qe7ee5 not found: key not found

The UI shows a generic explanation: "This usually means the XChain Hash ID is invalid or was computed with incorrect parameters. The hash may need to be recomputed from the original deposit receipt."
This message is misleading — the actual cause appears to be that the Terra Classic account does not exist on-chain because it has never received any LUNC. Terra Classic requires an account to have funds before it can sign transactions.
Disconnecting and reconnecting both wallets does not resolve the issue.

Resolved Submit Params (from error panel)

destChain: Terra Classic (0x00000001)
bridge: terra18m02l2f43c2dagqnz3kfccpgz9pzzz5hk915mh5wvr6dcvv47zfqdfs7la
nonce: 13
amount: 995000000000000000000
token(address): 0x24c79c6a00cdedddb81377b0b98dbb0fdf917fce
destAccount(address): 0xfe40f38958efc3c0d3de9076601d4460cf731555

Severity

Medium — Transfer is stuck and the error message does not guide the user toward resolution. Funds are not at risk (deposit exists, hash can be resubmitted once the wallet is funded), but the UX is confusing. The Faucet page already shows "No LUNC for gas" for zero-balance Terra wallets (#21), so a similar pre-check or clearer error message could be applied to the submit flow.

Suggested Improvements

Before attempting hash submission on Terra Classic, check if the connected wallet account exists on-chain (has LUNC balance). If not, show a clear message like: "Your Terra Classic wallet has no LUNC. You need LUNC to pay gas fees for the withdrawal transaction. Fund your wallet and try again."
When the RPC returns code = NotFound with key not found, catch this specific error and display a user-friendly message instead of the generic hash-recomputation suggestion.
Consider linking to the Faucet page or providing instructions for obtaining LUNC for gas.

Similar pattern to the zero-balance faucet fix in PR #34. The fix would be checking luncBalance from the wallet store before attempting hash submission on Terra. If zero, show a clear message like 'Your Terra wallet has no LUNC for gas — fund your wallet and retry' instead of the generic hash recomputation error. Can take this one.

Verified fixed — MR !141 added LUNC balance check before hash submission on Terra. If wallet has no LUNC, shows clear error message instead of generic hash recomputation error.
