Added an intel system to track other players’ activities. The Intel component displays flight plans from other players, showing their ships, routes, and timing. This data is fetched from the API and stored in Dexie for historical tracking.

Implemented caching for API calls to reduce rate limiting issues. Market data and flight plans are now cached with configurable TTLs. Extracted a reusable getCachedResponse pattern for consistent caching across different endpoints.

Enhanced the strategy system - ships now spawn with the correct machine based on their configured strategy. The spawnShipMachine handles dynamic machine selection between trade and halt behaviors.

Added profit metrics tracking with cost and profit columns in the trades view. The toolbar now shows an intel icon with quick access to the intel view. Various UI fixes including column widths and delayed updates to reduce flickering.
