feat: Add professional web-based optimization dashboard

Complete dashboard UI for controlling and monitoring optimization runs.

Backend API (Flask):
- RESTful endpoints for study management
- Start/stop/resume optimization runs
- Real-time status monitoring
- Configuration management
- Visualization data endpoints

Frontend (HTML/CSS/JS + Chart.js):
- Modern gradient design with cards and charts
- Study list sidebar with metadata
- Active optimizations monitoring (5s polling)
- Interactive charts (progress, design vars, constraints)
- Trial history table
- New optimization modal
- Resume/delete study actions

Features:
- List all studies with trial counts
- View detailed study results
- Start new optimizations from UI
- Resume existing studies with additional trials
- Real-time progress monitoring
- Delete unwanted studies
- Chart.js visualizations (progress, DVs, constraints)
- Configuration file selection
- Study metadata tracking

Usage:
  python dashboard/start_dashboard.py
  # Opens browser to http://localhost:5000

Dependencies:
  flask, flask-cors (auto-installed)

+# Atomizer Dashboard
+
+Professional web-based dashboard for controlling and monitoring optimization runs.
+
+## Features
+
+### Study Management
+- **List all studies** - View all optimization studies with metadata
+- **Resume studies** - Continue existing studies with additional trials
+- **Delete studies** - Clean up old/unwanted studies
+- **Study details** - View complete history, results, and metadata
+
+### Optimization Control
+- **Start new optimizations** - Configure and launch optimization runs
+- **Real-time monitoring** - Track progress of active optimizations
+- **Configuration management** - Load and save optimization configs
+
+### Visualization
+- **Progress charts** - Objective values over trials
+- **Design variable plots** - Track parameter evolution
+- **Constraint visualization** - Monitor constraint satisfaction
+- **Running best** - See convergence progress
+
+### Results Analysis
+- **Best results cards** - Quick view of optimal solutions
+- **Trial history table** - Complete trial-by-trial data
+- **Export capabilities** - Download results in CSV/JSON
+
+## Installation
+
+1. Install dependencies:
+```bash
+cd dashboard
+pip install -r requirements.txt
+```
+
+2. Start the dashboard server:
+```bash
+python api/app.py
+```
+
+3. Open your browser to:
+```
+http://localhost:5000
+```
+
+## Quick Start
+
+### Method 1: Using the launcher script
+```bash
+cd C:\Users\antoi\Documents\Atomaste\Atomizer
+python dashboard/start_dashboard.py
+```
+
+### Method 2: Manual start
+```bash
+cd dashboard
+python api/app.py
+```
+
+The dashboard will automatically open in your default browser at `http://localhost:5000`
+
+## Usage
+
+### Starting a New Optimization
+
+1. Click "New Optimization" button
+2. Enter study name
+3. Set number of trials
+4. Select configuration file
+5. Optionally check "Resume existing" if continuing a study
+6. Click "Start Optimization"
+
+### Viewing Study Results
+
+1. Click on a study in the sidebar
+2. View summary cards showing best results
+3. Examine charts for optimization progress
+4. Review trial history table for details
+
+### Resuming a Study
+
+1. Select the study from the sidebar
+2. Click "Resume Study"
+3. Enter number of additional trials
+4. Optimization continues from where it left off
+
+### Monitoring Active Optimizations
+
+Active optimizations appear in the sidebar with:
+- Real-time progress bars
+- Current trial number
+- Status indicators
+
+## API Endpoints
+
+### Studies
+- `GET /api/studies` - List all studies
+- `GET /api/studies/<name>` - Get study details
+- `DELETE /api/studies/<name>/delete` - Delete a study
+
+### Optimization
+- `POST /api/optimization/start` - Start new optimization
+- `GET /api/optimization/status` - Get all active optimizations
+- `GET /api/optimization/<name>/status` - Get specific optimization status
+
+### Configuration
+- `GET /api/config/load?path=<path>` - Load config file
+- `POST /api/config/save` - Save config file
+
+### Visualization
+- `GET /api/results/visualization/<name>` - Get chart data
+

+## Technology Stack
+
+- **Backend**: Flask (Python)
+- **Frontend**: Vanilla JavaScript + Chart.js
+- **Styling**: Modern CSS with gradients and shadows
+- **Charts**: Chart.js for interactive visualizations
+
+## Features in Detail
+
+### Real-time Monitoring
+The dashboard polls active optimizations every 5 seconds to show:
+- Current trial number
+- Progress percentage
+- Status (running/completed/failed)
+
+### Study Persistence
+All studies are stored in SQLite databases with:
+- Complete trial history
+- Optuna study state
+- Metadata (creation date, config hash, resume count)
+
+### Configuration Detection
+The system automatically detects when a study configuration has changed:
+- Warns when resuming with different geometry
+- Calculates MD5 hash of critical config parameters
+- Helps prevent invalid resume operations
+
+## Troubleshooting
+
+### Dashboard won't start
+- Check that Flask is installed: `pip install flask flask-cors`
+- Ensure port 5000 is not in use
+- Check firewall settings
+
+### Can't see studies
+- Verify optimization_results folder exists
+- Check that studies have metadata files
+- Refresh the studies list
+
+### Charts not showing
+- Ensure Chart.js loaded (check browser console)
+- Verify study has trial history
+- Check API endpoints are responding
+
+## Future Enhancements
+
+- [ ] Multi-objective Pareto front visualization
+- [ ] Export results to PDF/Excel
+- [ ] Optimization comparison tool
+- [ ] Parameter importance analysis
+- [ ] Surrogate model visualization
+- [ ] Configuration editor UI
+- [ ] Live log streaming
+- [ ] Email notifications on completion
+
+## Support
+
+For issues or questions:
+1. Check the console for error messages
+2. Verify API is running (`http://localhost:5000/api/studies`)
+3. Review optimization logs in the console
