Description / Intuition

• bumps abacus
• addressed breaking abacus changes (just a variable name change from fillsHistory to historical
• replace margin value with newly available abacus-calculated value on overview screen and market position screen
• showing "none" for certain liquidation price cases (see all the screen shots and left column explainers
• update adjust margin cta button to read "remove margin" when remove is the selected option
• update market position overview card design to match figma
• fix bug where open adjust margin -> select remove margin -> close adjust margin -> reopen and "add margin" is pre-selected
• display position margin as $ instead of % in receipt
