Summary:
This pull request enhances the OceanNodeStatus by including the escrow contract address for each supported blockchain network. It introduces a new type AddressPerChain to represent a map of chain IDs to their respective escrow addresses and populates this field in the status handler by iterating through configured networks.

Comments:
• [INFO][other] It would be beneficial to add a unit test for statusHandler.ts to ensure that the escrowAddress field is correctly populated for all supported chains in the OceanNodeStatus output. This helps verify the new functionality and prevents regressions.
