UX: As a user, I want to know my open liquidity positions on Uniswap V3

[kkennis]

Tasks #52 and #55 describe the 'action' space for the Uniswap V3 liquidity lifecycle - add and remove. But there is an intermediate, passive flow here as well - portfolio management. This is the ending page for the Add flow - seeing the stats of an open position - and the starting page for the Remove flow - seeing an open position and choosing to action it (i.e. remove the liquidity).

This is also where we have the chance to show unique stats and insights re: a liquidity position on Uniswap V3. For May 5, we will only do basic insights - increasing the 'business intelligence' narrative and providing advanced analytics (for instance, time-series data) will be a post May 5 effort.

As starting point, the 'portfolio manager' screen should show:

• All open and closed positions
• Amount of liquidity in the position
• Fees accrued in position
• Current price of pool
• Whether position is active or not

ALL OTHER STATS ARE OUT OF SCOPE, as are 'position details' screen with time series data like the IL calculator.

Acceptance Criteria:

• Page exists where user sees all open and closed positions
• For each position, user can see stats specified above
• For open positions, user has button where they can trigger the 'Remove liquidity' flow
