Make UPnP more robust - Once a random port was mapped, we try to stick to it even if a UPnP refresh fails. Previously we were immediately moving back to try the default port, leading to frequent ENR changes. - We were deleting port mappings before refresh as a possible workaround. This created issues in some UPnP servers. The UPnP (and PMP) specification is explicit about the refresh requirements, and delete is clearly not needed (see https://github.com/ethereum/go-ethereum/pull/30265#issuecomment-2766987859). From now on we only delete when closing. - We were trying to add port mappings only once, and then moved on to random ports. Now we insist a bit more, so that a simple failed request won't lead to ENR changes.
