Update global faucet rate limit to 40 requests/hour rather than the current 20, after Core got blocked.

https://app.datadoghq.com/s/zk39ngefvty1feg8/8xx-mzs-tqe

shows that we have been blocking faucet requests.  Today (2025-08-26) Core reported the blockage (for the first time as far as I know). 

We have been blocking more than 20 requests/hour but if something (e.g Core) keeps retrying on failure, 20 additional requests may be enough to clear all of them.
