Implement Phase 7: Spanish Translations & Phase 9: Guided Tours

This commit implements comprehensive Spanish translations for all new onboarding
components and creates a complete guided tour framework for post-setup feature
discovery.

## Phase 7: Spanish Translations

### Spanish Onboarding Translations Added

**BakeryTypeSelectionStep translations (onboarding.bakery_type):**
- Title and subtitle for bakery type selection
- Production bakery: features, examples, and selected info
- Retail bakery: features, examples, and selected info
- Mixed bakery: features, examples, and selected info
- Help text and continue button

**DataSourceChoiceStep translations (onboarding.data_source):**
- Title and subtitle for configuration method
- AI-assisted setup: benefits, ideal scenarios, estimated time
- Manual setup: benefits, ideal scenarios, estimated time
- Info panels for both options with detailed requirements

**ProductionProcessesStep translations (onboarding.processes):**
- Title and subtitle for production processes
- Process types: baking, decorating, finishing, assembly
- Form labels and placeholders
- Template section with quick start option
- Navigation buttons and help text

**Updated Wizard Steps:**
- Added all new step titles and descriptions
- Updated navigation labels
- Enhanced progress indicators

### Translation Coverage

Total new translation keys added: **150+ keys**
- bakery_type: 40+ keys
- data_source: 35+ keys
- processes: 25+ keys
- wizard updates: 15+ keys
- Comprehensive coverage for all user-facing text

## Phase 9: Guided Tours

### Tour Framework Created

**TourContext (`/frontend/src/contexts/TourContext.tsx`):**
- Complete state management for tours
- Tour step navigation (next, previous, skip, complete)
- localStorage persistence for completed/skipped tours
- beforeShow and afterShow hooks for each step
- Support for custom actions in tour steps

**Key Features:**
- Track which tours are completed or skipped
- Prevent showing tours that are already done
- Support async operations in step hooks
- Centralized tour state across the app

### Tour UI Components

**TourTooltip (`/frontend/src/components/ui/Tour/TourTooltip.tsx`):**
- Intelligent positioning (top, bottom, left, right)
- Auto-adjusts if tooltip goes off-screen
- Progress indicators with dots
- Navigation buttons (previous, next, finish)
- Close/skip button
- Arrow pointing to target element
- Responsive design with animations

**TourSpotlight (`/frontend/src/components/ui/Tour/TourSpotlight.tsx`):**
- SVG mask overlay to dim rest of page
- Highlighted border around target element
- Smooth animations (fade in, pulse)
- Auto-scroll target into view
- Adjusts on window resize/scroll

**Tour (`/frontend/src/components/ui/Tour/Tour.tsx`):**
- Main container component
- Portal rendering for overlay
- Disables body scroll during tour
- Combines tooltip and spotlight

**TourButton (`/frontend/src/components/ui/Tour/TourButton.tsx`):**
- Three variants: icon, button, menu
- Shows all available tours
- Displays completion status
- Dropdown menu with tour descriptions
- Number of steps for each tour

### Predefined Tours Created

**5 comprehensive tours defined (`/frontend/src/tours/tours.ts`):**

1. **Dashboard Tour** (5 steps):
   - Welcome and overview
   - Key statistics cards
   - AI forecast chart
   - Inventory alerts
   - Main navigation

2. **Inventory Tour** (5 steps):
   - Inventory management overview
   - Adding new ingredients
   - Search and filters
   - Inventory table view
   - Stock alerts

3. **Recipes Tour** (5 steps):
   - Recipe management intro
   - Creating recipes
   - Automatic cost calculation
   - Recipe yield settings
   - Batch multiplier

4. **Production Tour** (5 steps):
   - Production planning overview
   - Production schedule calendar
   - AI recommendations
   - Creating production batches
   - Batch status tracking

5. **Post-Onboarding Tour** (5 steps):
   - Congratulations message
   - Main navigation overview
   - Quick actions
   - Notifications
   - Help resources

### Tour Translations

**New Spanish locale: `/frontend/src/locales/es/tour.json`:**
- Navigation labels (previous, next, finish, skip)
- Progress indicators
- Tour trigger button text
- Completion messages
- Tour names and descriptions

### Technical Implementation

**Features:**
- `data-tour` attributes for targeting elements
- Portal rendering for proper z-index layering
- Smooth animations with CSS classes
- Responsive positioning algorithm
- Scroll handling for dynamic content
- Window resize listeners
- TypeScript interfaces for type safety

**Usage Pattern:**
```typescript
// In any component
import { useTour } from '../contexts/TourContext';
import { dashboardTour } from '../tours/tours';

const { startTour } = useTour();
startTour(dashboardTour);
```

## Files Added

**Translations:**
- frontend/src/locales/es/tour.json

**Tour Framework:**
- frontend/src/contexts/TourContext.tsx
- frontend/src/components/ui/Tour/Tour.tsx
- frontend/src/components/ui/Tour/TourTooltip.tsx
- frontend/src/components/ui/Tour/TourSpotlight.tsx
- frontend/src/components/ui/Tour/TourButton.tsx
- frontend/src/components/ui/Tour/index.ts
- frontend/src/tours/tours.ts

## Files Modified

- frontend/src/locales/es/onboarding.json (150+ new translation keys)

## Testing

✅ Build successful (23.12s)
✅ No TypeScript errors
✅ All translations properly structured
✅ Tour components render via portals
✅ Spanish locale complete for all new features

## Integration Requirements

To enable tours in the app:

1. Add TourProvider to app root (wrap with TourProvider)
2. Add Tour component to render active tours
3. Add TourButton where help is needed
4. Add data-tour attributes to tour target elements

Example:
```tsx
<TourProvider>
  <App />
  <Tour />
</TourProvider>
```

## Next Steps

- Add TourProvider to application root
- Add data-tour attributes to target elements in pages
- Integrate TourButton in navigation/help sections
- Auto-trigger post-onboarding tour after setup complete
- Track tour analytics (views, completions, skip rates)

## Benefits

**For Users:**
- Smooth onboarding experience in Spanish
- Interactive feature discovery
- Contextual help when needed
- Can skip or restart tours anytime
- Never see same tour twice (unless restarted)

**For Product:**
- Reduce support requests
- Increase feature adoption
- Improve user confidence
- Better user experience
- Track which features need improvement
