feat: Add advanced features and visual configuration editor

[foXaCe]

Description :

State mapping (now with improved warning system)

state_map:
- value: "on"
label: "Active"
- value: "off"
label: "Inactive"

🚀 Features Added

Advanced Chart Types

• Stacked Area Charts: Visualize cumulative data with smooth layered areas
• Candlestick Charts: Financial data visualization with OHLC support
• Multi-Axis Charts: Display multiple data series with different Y-axis scales

Visual Configuration Editor

• GUI-based configuration: Replace YAML editing with intuitive visual interface
• Real-time preview: See changes instantly while configuring
• Form validation: Prevent configuration errors with built-in validation
• Better UX: Drag-and-drop, color pickers, and interactive controls

Intelligent Caching System

• Memory Cache: LRU-based caching with automatic eviction (50MB limit)
• Disk Cache: Persistent storage with compression (200MB limit)
• Smart Prefetching: Predictive data loading based on usage patterns
• Performance Metrics: Real-time cache hit rates and monitoring

Interactive Zoom & Pan

• Touch Support: Pinch-to-zoom and pan gestures on mobile devices
• Mouse Controls: Wheel zoom and drag-to-pan with desktop mouse
• Configurable Limits: Custom min/max zoom levels (0.1x to 10x)
• Smooth Animations: Fluid transitions with cubic-bezier easing

Enhanced Micro-interactions

• Visual Feedback: Subtle animations for user actions (optional)
• Hover Effects: Enhanced data point interactions
• Loading States: Smooth loading animations
• Error Handling: Visual feedback for errors and connectivity issues

🔧 Technical Improvements

• Modular Architecture: Clean separation of features in dedicated modules
• ESLint Compliance: All code follows project linting standards
• Memory Management: Proper cleanup and leak prevention
• Performance Optimized: Reduced bundle size despite new features
• Backward Compatible: All existing configurations continue to work

🐛 Bug Fixes

• Fixed automatic animations that triggered without user interaction
• Improved performance monitoring to prevent animation loops
• Better error handling and resource cleanup

📋 Configuration Examples

Enable Advanced Features

type: custom:mini-graph-card
entity: sensor.temperature
# New features (all optional)
zoom_pan_enabled: true
enable_zoom: true
enable_pan: true
min_zoom: 0.5
max_zoom: 20
cache: true
chart_type: line  # or 'stacked_area', 'candlestick', 'multi_axis'

Visual Editor

The card now includes a visual configuration editor accessible through the Lovelace UI, eliminating
 the need for manual YAML editing in most cases.

🔄 Migration Guide

This update is fully backward compatible:
- Existing configs: All current YAML configurations work without changes
- New features: Opt-in only, nothing changes by default
- Performance: Same or better performance for existing setups

📦 Files Changed

- src/main.js - Core integration of all new features
- src/advancedChartsSimple.js - Advanced chart rendering engine
- src/intelligentCacheSimple.js - Caching system implementation
- src/zoomPanSimple.js - Zoom/pan controller
- src/microInteractionsSimple.js - Enhanced user interactions
- src/editor.js - Visual configuration editor
- package.json - Updated build scripts and linting
- dist/ - Updated compiled bundles

🧪 Testing

- ✅ All existing functionality preserved
- ✅ New features work independently
- ✅ ESLint passes on all modules
- ✅ Build process succeeds
- ✅ No breaking changes detected

This pull request significantly enhances the mini-graph-card while maintaining full backward
compatibility and adding a much-requested visual configuration interface.

Thanks for the contribution!
Suggest you to split your PR to small ones (one per a small task).

And please have a look at other PRs with similar features. There is one almost done visual editor #1128, or several discussions on how to add grid support, e.g. #1199. Unfortunately, we were short on time lately to get these merged. So, we shouldn't start competing PRs.

Thanks for all the useful suggestions in your PR!
