[DEV] Update farming contracts on frontend

[chimera-defi]

• The frontend currently has code to support master chef contracts in geyserv2 on the earn page.
• All of our current farming contracts use masterchef
• We need to update all UI modals on the earn page to the new master chef contract and the related pools for sgt-eth, veth-weth and veSGT
• The code is already there, just needs to be wired up properly
