Big day of bug fixes and stability improvements. Added automatic retry logic for 429 (rate limit) responses from the API, with exponential backoff. Improved caching and throttling to reduce API calls and stay within rate limits.

Ships now sell excess cargo before starting new trade routes - fixing an issue where leftover goods from failed trades would block cargo space. Added shouldCheckStrategy to properly handle strategy switches mid-operation.

Fixed the reset flow to properly clear all database tables, and persist flight plans across sessions. Probes now visit locations by shortest distance instead of random selection. Excluded research goods from trading until proper handling is implemented.

Increased max ships to 70-80 for larger fleets. Various UI fixes including activity visibility, row keys, and layout improvements. Added wait-on-error behavior to prevent machines from spinning on repeated failures.
