Portfolio % & Live Position Data

Every trade in the feed now shows what percentage of the trader's portfolio it represents — right below the trade size. A $50K trade from a $5M portfolio (1%) hits different than the same trade from a $50K portfolio (100%). Portfolio percentage is computed at trade time and stored as a snapshot, so you can filter by conviction level. The Pos column now shows real-time share counts formatted like Polymarket (comma-separated with full precision), and position data is fetched immediately when a whale trade is detected instead of waiting for the next sync cycle. Kalshi trades now display the traded outcome and share count instead of an empty cell.
