Recipe detail page, menu revamp, and UX improvements

- Add recipe detail page (recipe.html) with full ingredients and instructions
- Simplify menu tab: cards show name + description only, click through for full recipe
- Add description field to Recipe model with DB migration
- Add AI-generated descriptions to menu, swap, and import prompts
- Add single dish by description (POST /api/menus/current/recipes)
- Add grocery item delete without pantry add (DELETE /api/grocery/{id}/items)
- Persist grocery checked state server-side (PATCH /api/grocery/{id}/check-item)
- Hash-based tab routing — refresh stays on current tab
- Logo branding in header and favicon
- Dark theme fixes: URL/text inputs, amber accent, muted danger/warning colors
- Markdown rendering in chat (bold, italic, code blocks, lists, headers)
- Fix instruction step splitting for inline-numbered steps (1. 2. 3.)
- Import recipe from URL with JSON-LD structured data + AI fallback
