Add an option to show the retry button on all pending tx

**What problem are you trying to solve?**
I usually send multiple transactions with low urgency and a low gas price. When I have a few transactions that cannot go through, I want to increase the gas price on all of them. Metamask forces me to wait for every confirmation until I can resend the next tx. This is obviously very annoying and time consuming for transactions that take more than a few minutes.

**Describe the solution you'd like**
Add an option to enable resubmitting every tx for advanced users that understand that there might be a transaction with a lower nonce blocking.

**Additional context**
I understand this goes against #4926. But as that seems to be about not confusing users that don't understand nonces, an option to enable this would do no harm

Start by reviewing the current pending-transaction retry flow and issue #4926 to understand the nonce-safety concerns. Define how an advanced-user option would expose retry controls for all pending transactions, including the warning and behavior when a lower nonce remains blocking; completion should be demonstrated through focused UI and transaction-flow tests.
