Small Improvements

Fixed an issue where Passenger Services set to 'create-job' could fail or create invalid jobs when handling large passenger groups. The system now correctly splits passenger loads into multiple jobs respecting the 20-passenger charter limit and prevents a job from being created for any single group that exceeds this limit.
Fixed a critical issue where an aircraft could become stuck at its destination if you lost access to the arrival slot mid-flight (e.g., if a partnership was dissolved). Your aircraft will now be safely auto-stored or placed on the tarmac, allowing the job to complete.
Improved the reliability of partnership dissolutions to ensure all airport assets are handled correctly.
