fix(stake): deposit-first yield source tiles, drop the real-gas line

Community feedback (willywonka): users deposit regular USDC/stETH —
Morpho/Morpheus is only the yield source. Tile title becomes the
deposit ("Deposit USDC"), the protocol moves to the source line
("yield via Morpheus · in MOR"). Also removes the "Ethereum mainnet —
real gas" sentence from the amber note, keeping the 7-day lock fact.
