Validate network before creating transactions

[bagelface]

There are currently many buttons across the site that do not validate the user is on the current network before creating and submitting a transaction for approval. A few instances of this that I've noticed, but this is my no means exhaustive:

• Voting on a prop
• Delegating votes
• Canceling votes on a prop

Most of these transactions do not involve sending ETH, which is the worse case scenario for an issue like this (a user that's connected to the wrong network approves a transaction that sends value to an address on a network where there is nothing deploy, which is very like to result in unrecoverable funds). However, it could result in users accidentally sending multiple transactions on the incorrect network and wasting gas funds.

I'd suggest one of two solutions for this: (1) Create a base component for buttons that create transactions and do validation there or (2) validating on page load and creating a blocking modal that prompts the user to switch to the correct network.
