Implement REQ-UI-SHIP-BEHAVIOR: show selected ship's current behavior

Add a live behavior label to the ship stats panel that names the ship's
top-priority behavior (Retreating/Engaging/Salvaging/Repairing/Rallying/
Standby/Advancing) as resolved by the AiSystem selection pass. Wired into
both the in-game selected building panel and the balancing InspectWindow,
for player and enemy ships. The label is hidden in the static design
preview.
