fill_rate accessor returned decimal (0.33) instead of percentage (33),
causing progress bars to display at ~1% width. DevSeeder hard-coded
status='full' on EHBO za_dag despite only 1/4 slots filled, and factory
assignments now respect slots_open_for_claiming. Added post-assignment
status auto-correction based on actual fill counts.
