fix: increase pending transaction timeout

[noot]

• increase the pending transaction timeout from 30s to 60s.
• also check if the tx was included after the retry loop sleep, in which case, return
• based on the chain of errors logs, it appeared the pending transaction was timing out after 30s, so it was then retried with Retrying with bumped fees..., however the tx was included in between the time it timed out and when the retry was started, so the second submission failed
