Mesa halves the coinbase from 720 to 360 MINA, so a Berkeley-era --minimum-block-reward threshold silently turns every won slot into an empty block. The daemon has no startup warning until MinaProtocol/mina#18919 lands, so document the check in the post-upgrade block producer tab.

Mesa halves the coinbase from 720 MINA to 360 MINA, so a
--minimum-block-rewardthreshold that was fine on Berkeley is likely above the new coinbase. The producer still wins its slot but emits an empty block with no coinbase and no fees, so block production looks healthy while the operator earns nothing.The daemon has no startup warning for this yet — MinaProtocol/mina#18919 adds one but is not merged — so this adds a caution to the Block Producer tab of the Mesa post-upgrade page.
