Note

Low Risk
Low risk: this only extends the MULTICALL_CONTRACT_BY_CHAINID mapping to enable multicall batching on an additional chain, with no behavioral changes for existing networks.

Overview
Adds Tempo Mainnet support to multicall-based RPC batching by registering chain 0x1079 in MULTICALL_CONTRACT_BY_CHAINID.

Updates the assets-controllers changelog to note the newly supported Tempo Mainnet multicall contract.
