Two follow-up seed scripts after the main demo reset:
1. seed_work_centres.py: creates one fp.work.centre per existing
fusion.plating.work.center (matched by code), classifying kind
from name/code keywords. Then backfills work_centre_id on every
fp.job.step whose recipe_node has a legacy work_center_id with
a matching native code. Plant Overview kanban now has columns
instead of one big 'Unassigned' bucket.
2. seed_part_coatings.py: assigns existing fp.coating.config rows
(with recipes) to up to 20 bare fp.part.catalog rows
round-robin. Field on the part is x_fc_default_coating_config_id.
Future SO confirms via these parts will naturally generate full
recipe-linked steps via _generate_steps_from_recipe.
Both idempotent — re-running creates nothing new.
Run on entech: 9 native work centres created, all 234 existing
fp.job.step rows bound. Parts with coating: 2 -> 22 (28 -> 8 bare).
