fix: bugs in add network modal

[bergeron]

Description

Fixes 2 bugs in the add network modal:

• When clicking the "Review" button to compare the old vs new RPC urls, the new url was hardcoded to https://flashbots.polygon-mainnet.com here. This code seems WIP code, but got shipped to prod. For now I have disabled this Review button until the actual data can be passed into the component.

• When adding a popular network, it would say You're adding this network to MetaMask and giving Undefined dapp origin permission to use it.. This message should only appear when dapps add networks, not when adding from the popular list.
