[Feature] Build POOL$GEAR functionality into Exchange page

[nickcaputo]

This ticket is to implement the POOL$GEAR function within the swap for liquidity providing, but NOT the display of it or the swap functionality. ONLY create the functionality to provide $WETH + $ROBOT from wallet into a liquidity pool, and receive $GEAR into that same wallet.

if i understand it correctly for this we should use pool provided from metafactory?

as mentioned in the RAID doc https://gov.metafactory.ai/t/proposal-metafactory-dashboard/243 :

Will leverage new V2 pool from iROBOT, when available
