feat: Implement comprehensive promoter system with dashboard and role-based access

This commit implements a complete promoter system that allows professional users
(is_professionnal: true) to manage events with advanced analytics and controls.

## Key Features Added:

### Role-Based Access Control
- Update User#can_manage_events? to use is_professionnal field
- Add promoter? alias method for semantic clarity
- Restrict event management to professional users only

### Enhanced Navigation
- Add conditional "Créer un événement" and "Mes événements" links
- Display promoter navigation only for professional users
- Include responsive mobile navigation with appropriate icons
- Maintain clean UI for regular users

### Comprehensive Promoter Dashboard
- Revenue metrics with total earnings calculation
- Tickets sold counter across all events
- Published vs draft events statistics
- Monthly revenue trend chart (6 months)
- Recent events widget with quick management actions
- Recent orders table with customer information

### Advanced Analytics
- Real-time revenue calculations from order data
- Monthly revenue trends with visual progress bars
- Event performance metrics and status tracking
- Customer order history and transaction details

### Event Management Workflow
- Verified existing event CRUD operations are comprehensive
- Maintains easy-to-use interface for event creation/editing
- State management system (draft → published → cancelled)
- Quick action buttons for common operations

### Documentation
- Comprehensive implementation guide in docs/
- Technical details and architecture explanations
- Future enhancement recommendations
- Testing and deployment considerations

## Technical Implementation:

- Optimized database queries to prevent N+1 problems
- Proper eager loading for dashboard performance
- Responsive design with Tailwind CSS components
- Clean separation of promoter vs regular user features
- Maintainable code structure following Rails conventions

+# Promoter System Implementation
+
+This document outlines the comprehensive promoter system implemented for AperoNight, providing professional event organizers with powerful tools to manage their events and track their performance.
+
+## Overview
+
+The promoter system allows professional users (marked with `is_professionnal: true`) to create, manage, and analyze their events through a dedicated interface. This system includes:
+
+- **Role-based access control** - Only professional users can manage events
+- **Comprehensive dashboard** - Real-time metrics and revenue tracking
+- **Event management workflow** - Easy CRUD operations for events
+- **Revenue analytics** - Monthly revenue trends and detailed metrics
+
+## Key Features Implemented
+
+### 1. User Role Management
+
+**File**: `app/models/user.rb`
+
+The system uses the existing `is_professionnal` boolean field to determine promoter privileges:
+
+```ruby

+
+### 2. Conditional Navigation
+
+**File**: `app/views/components/_header.html.erb`

+
+### 4. Event Management Workflow
+
+The existing event management system provides:
+
+#### Event Creation

+- **State Management**: Clean state transitions
+- **Rollback Capability**: Can unpublish if needed
+
+## Technical Implementation Details
+
+### Database Schema
+
+The system leverages existing database structure:
+- **Users Table**: `is_professionnal` boolean field
+- **Events Table**: Belongs to user, has states enum
+- **Orders Table**: Links to events and users
+- **Tickets Table**: Links to orders and events
+
+### Revenue Calculations
+
+Revenue metrics are calculated with optimized queries:
+
+```ruby
+# Total revenue across all promoter events
+@total_revenue = current_user.events
+                            .joins(:orders)
+                            .where(orders: { status: ['paid', 'completed'] })
+                            .sum('orders.total_amount_cents') / 100.0
+
+# Monthly revenue trend (6 months)
+@monthly_revenue = (0..5).map do |months_ago|
+  start_date = months_ago.months.ago.beginning_of_month
+  end_date = months_ago.months.ago.end_of_month
+  
+  revenue = current_user.events
+                       .joins(:orders)
+                       .where(orders: { status: ['paid', 'completed'] })
+                       .where(orders: { created_at: start_date..end_date })
+                       .sum('orders.total_amount_cents') / 100.0
+  
+  { month: start_date.strftime("%B %Y"), revenue: revenue }
+end.reverse
+```
+
+### Security & Authorization
+
+- **Controller Guards**: `before_action :ensure_can_manage_events!`
+- **Model-level Checks**: User role validation in models
+- **View-level Conditionals**: UI elements only shown to authorized users
+- **Route Protection**: Promoter namespace requires authentication
+
+### Performance Optimizations
+
+- **Eager Loading**: `includes(:orders, :tickets)` to prevent N+1 queries
+- **Efficient Queries**: Database-level aggregations for metrics
+- **Caching Ready**: Structure allows for future caching implementation
+- **Paginated Results**: Large datasets handled efficiently
+
+## User Experience Enhancements
+
+### Dashboard Design Philosophy
+- **Information Hierarchy**: Most important metrics prominently displayed
+- **Progressive Disclosure**: Detailed information available on demand
