### Summary of Changes
- Added 'Get Prompt' button and ProductBomPromptModal dialog on /products/:id/bom.
- Formats product ID, variants, and raw material inventory into a structured prompt for LLMs.
- Fixed backend bug in GET /products/:id?lang=all that wiped product.name when no translations existed.
- Added multi-level fallback in frontend to ensure product name never shows 'Unknown Product'.
