Partnership Route Sync Fixes

We have improved the logic that determines when routes are enabled or disabled during partnership changes to ensure immediate accuracy.

• Leaving: When a company leaves a partnership, both the leaving company and the remaining partners instantly lose access to each other's slots. Routes relying on those shared slots will now correctly disable.
• Joining: When a new company joins, existing partners' invalid routes are immediately re-checked and enabled if the new member provides the necessary slots.
