Changes proposed in this pull request

• Work-order priority now controls Builder selection, with claimed orders processed before unclaimed orders and work-order ID breaking "ties".
• The Builder hut shows work in priority order (with all claimed work ahead of any work available to be assigned when in manual mode).
• The current work order border is highlighted in green for a visual signal of the current job.

Testing

• Assigned multiple builds to a builder, then reordered the priority in the town hall. Observed that the builder moved on to the reordered "next priority" rather than picking the building in the sequence the builds were requested.
• Verified builder hut ordering matched priority order.
• Verified "available" work orders were present when the builder was in manual mode, and appeared after all assigned/claimed work orders.
• Verified priority persisted through a restart

Review please
