Add recipe suggestions, chat tab, and major workflow improvements

- Replace 7-day grid menu with browsable recipe suggestion cards (swap, remove, make this)
- Add Chat tab: conversational AI with full pantry/menu/grocery context
- Grocery list works without a menu (pantry-only mode)
- Individual grocery checkboxes auto-add items to pantry
- Swap modal with optional preference input
- User notes textarea on menu and grocery generation
- Clear button for menu and grocery list
- LLM notes/summary displayed after generation, persisted to DB
- Favicon linked in HTML
- Category dropdown styled for dark theme
- System prompt configurable via SYSTEM_PROMPT in .env
- Fix startup error (ollama_timeout default), DB migration for menu_plans.notes
- Simplify: batch N+1 queries, extract _current_monday(), merge chat sync fns,
  asyncio.get_running_loop(), fix currentGroceryId bug, cap chat history
