feat(codes): code NOT NULL voor PBI/Story + Task.code + product_id denorm

Browse source 
- Pbi.code en Story.code worden NOT NULL (tot dusver optional)
- Task krijgt code String + product_id String denorm + @@unique([product_id, code])
- Product krijgt back-relation tasks Task[]
- Migratie backfillt bestaande NULL-rijen via PL/pgSQL:
  PBI-N (per product), ST-N (3-digit padded met GREATEST om
  truncatie van LPAD bij 4-digit nummers te voorkomen),
  T-N voor alle tasks
- Codes zijn stabiele identifiers (Jira-stijl flat-per-product),
  zodat re-parenting de code niet muteert
