The _compute_display_name method on fusion.plating.customer.spec was
missing its @api.depends decorator. Without it, Odoo doesn't know
when to fire the compute, so display_name stayed NULL on:
- All seeded specs (created via XML data import)
- Any spec created later (the field was never recomputed)
Symptom: Specification dropdown on the SO line showed "Unnamed" for
every option, making spec selection useless.
Fix:
- @api.depends('code', 'revision', 'name') on _compute_display_name
- Imported `api` (was only `fields, models`)
Companion entech-side action: forced recompute on the 15 existing
specs via `env.add_to_compute(specs._fields['display_name'], specs)`
so the stored column was backfilled. New specs created via UI will
trigger the compute automatically going forward.
