44313: DrawStatusPanel
Refreshes the crew-status display at the right side of the game window. Scans all 7 crew records starting at the alive-flag byte (29581 = $7386+7). For each crew member: if its crew-ID matches the alien's current target (33703) it is highlighted; if its alive flag is 0 (dead) the scan stops early (crew records are kept in alive-descending order). Live crew members get their portrait sprite drawn at the status panel position ($40A4 column).
