Add potential weekly yield in lock form

[alter-eggo]

Right now, we do show a yield tooltip for the BAL/WETH 80/20 pool with percentages.
I was thinking we could expand that into fiat / dollar amounts for the lock interaction.
Essentially:
Swap fees would remain constant regardless of the amount locked.
This means, the Potential weekly yield in most cases will never be $0.00
The Protocol revenue share and Voting incentives will rise and fall depending on the lock (since they are dependent on the user's veBAL)
