feat(plating): recipe-level cert suppression Booleans

Adds five requires_* Booleans on fusion.plating.process.node
(requires_coc, requires_thickness_report, requires_nadcap_cert,
requires_mill_test, requires_customer_specific), default True.

Recipe is SUPPRESS-ONLY: when False, the recipe never produces that
cert type even if the customer/part requested it. Default True =
existing recipes keep producing the same cert set they produce today.

Surfaced on recipe-level form (node_type == 'recipe'); resolver reads
from job.recipe_id which is always a top-level recipe node.

Post-migrate backfills NULL -> TRUE on existing nodes.

+"""Post-migrate for 19.0.22.0.0 — Recipe-level cert suppression Booleans.
+
+Backfills NULL -> TRUE on the five new requires_* columns on
+fusion.plating.process.node (requires_coc, requires_thickness_report,
+requires_nadcap_cert, requires_mill_test, requires_customer_specific).
+
+Default TRUE = inherit current behaviour for every existing recipe
+(zero migration surprises — every existing recipe keeps producing
+the same cert set it produces today).
+
+Idempotent: safe to re-run.
