Implement an x-bridge dashboard #706
Description
The dashboard
- must display the history of completed x-bridge transactions as well as the tokens and amounts in transit
- must display the amount of each bridged token locked in the token manager contract on the source chain
- must display each bridged token's circulating supply minted by the token manager contract on the target chain
- should display stats on the average gas fee spent on each target chain so that we can adjust the chain-specific flat fee if needed
