C-chain exports call newExportTxFromBaseFee with the caller-supplied base fee unpadded, unlike atomic imports which apply a 10% buffer to absorb base-fee volatility between signing and broadcast (CECHO-1821). This caused exports to broadcast with an underfunded fee once the C-chain base fee rose after signing, surfacing as an "insufficient funds" error despite adequate balance. Apply the same 10% padding used for imports to the export base fee. Ticket: CECHO-2004
