Add complete ESP32 Waveshare e-paper dashboard implementation for Home Assistant

[Copilot]

This PR implements a comprehensive Home Assistant dashboard solution for ESP32 microcontrollers with Waveshare e-paper displays, powered by ESPHome.

Overview

Provides a production-ready dashboard that displays real-time information from Home Assistant on low-power e-ink screens. Users can have a working dashboard in approximately 30 minutes.

What's Included

Core Implementation

Main Configuration (esp32-dashboard.yaml)

• Full-featured dashboard with time, date, weather, and sensor displays
• Support for multiple Waveshare e-paper display models (1.54" to 7.5")
• WiFi connectivity with fallback access point for initial setup
• Home Assistant API integration with encryption
• OTA (Over-The-Air) firmware updates
• Material Design Icons and custom font support (Roboto family)
• Configurable update intervals (default: 5 minutes)
• Manual refresh button accessible from Home Assistant

Example Configurations

Four ready-to-use example configurations for different use cases:

1. Basic (examples/esp32-dashboard-basic.yaml) - Minimal setup perfect for testing and learning
2. Weather (examples/esp32-dashboard-weather.yaml) - Weather-focused dashboard with detailed forecasts and icons
3. Small Display (examples/esp32-dashboard-small.yaml) - Optimized layouts for 2.9" and 2.13" displays
4. Battery Powered (examples/esp32-dashboard-battery.yaml) - Power-efficient configuration with deep sleep mode
