Pantry-first AI prompts, recipe editing, and grocery copyHEADmaster

- Rewrite menu generation to build recipes around existing pantry
  ingredients (max 4-5 extras per recipe); add in_pantry flag per
  ingredient for downstream accuracy
- Flip grocery list logic to ONLY include items not in the pantry,
  with explicit cross-check rule instead of include-everything default
- Strengthen no-menu grocery prompt to handle empty vs. stocked pantry
- Rewrite Commis chat system prompt to treat kitchen context as source
  of truth with explicit response rules per query type
- Align replacement/single-recipe prompts to prefer pantry coverage
- Update system_prompt default to reflect pantry-first identity
- Add PUT /api/recipes/:id endpoint for recipe editing
- Add inline edit mode to recipe detail page (name, type, ingredients,
  instructions, time, servings)
- Add Copy button to grocery list (exports markdown checklist)
