Split A1 category prompts canonically; retire attributes prompting

- Category enhance prompts (Sync A1 / seed-a1 / repair) now use the same
  three role sections as the rest of the platform: Title / Description /
  Meta. The retired "--- Attributes ---" role section is removed from the
  canonical template, the legacy-split overlay, and the web prompt editor;
  Category/Attrs stay as plain product-context lines (attribute extraction
  remains pipeline-level via AppendAttributeConstraints).
- Stored prompts still carrying an attributes section are detected by
  CategoryEnhancePromptNeedsRepair and rewritten on the next Sync.
- Legacy wp_product_categories.sql splits now also seed a default Slovenian
  metaTitle rule (dumps only carried <metaDescription>), so every A1
  category gets all four prompt areas: title formula, description
  sections, meta title, meta description.
- Role-sectioned prompts no longer imply the A1 SEO-omit cohort
  (CompanyOmitsSEOMeta): sectioned prompts are the canonical prompt-editor
  output for every tenant, and the sniff silently disabled SEO meta for
  any company that saved a category prompt.
- Verified locally: repair-category-prompts -apply updated 238 A1 +
  Platform Demo categories from scripts/seed/wp_product_categories.sql
  (216 legacy splits), idempotent on re-run, zero attributes sections
  left in DB.
