eth_getTransactionByHash on Polygon
Fetches a transaction's full details (from, to, value, input, gas) by its hash. Returns null if the transaction is unknown or still pending propagation.
Null covers both 'unknown' and 'still propagating', so treat it as 'not yet' and retry rather than 'never'. The blockNumber field stays null until the tx is mined — the cleanest pending-vs-mined check.
