Extends the existing post_init_hook to also do (idempotent) Sub 12a
work on first install / upgrade:
1. Backfill kind='step_input' on existing
fusion_plating_process_node_input rows where kind IS NULL.
2. Seed fp.step.template from the ENP-ALUM-BASIC recipe's child
nodes if the library is currently empty. Uses _STARTER_KIND_BY_NAME
to map recipe-step names to default_kind values, then calls
_seed_default_inputs() to populate the per-kind input rows.
3. Falls back to a 15-entry hard-coded minimal seed list if
ENP-ALUM-BASIC doesn't exist on the target DB.
All three operations no-op when the relevant state already exists.
