fix: Display MAE/MFE as dollars not percentages in analytics UI

- Changed 'Avg MFE: +X.XX%' to 'Avg MFE: +$X.XX'
- Changed 'Avg MAE: -X.XX%' to 'Avg MAE: -$X.XX'
- Database already stores dollar values (fixed Nov 19)
- UI was incorrectly displaying dollars with % suffix
- V8 trades: Avg MFE $34.23, Avg MAE -$11.06 (correct)
- Part of MAE/MFE data corruption fix series

Also corrected existing v8 trade in database:
- Before: MFE 19.73% (account %), MAE -1.53% (account %)
- After: MFE $95.11, MAE -$7.39 (actual dollars)
- SQL: UPDATE based on maxFavorablePrice/maxAdversePrice
