Complete ESP32InfoScreen controller implementation with enhanced hardware control and rate-limited communication

[Copilot]

This PR provides a comprehensive implementation of the ESP32InfoScreen controller, transforming it from a skeleton with TODO placeholders into a fully functional bidirectional communication system between ImSwitch and ESP32 devices with attached displays.

Key Features Implemented

🔄 Rate-Limited Communication System

Implemented a sophisticated rate limiting mechanism to prevent ESP32 serial communication issues:

• 0.5-second minimum intervals between updates to ESP32
• Pending update queue with Timer-based delayed sending
• Prevents communication overload while maintaining responsiveness

🎯 Enhanced Motor Control

Complete motor control implementation supporting multiple movement modes:

• Speed-based control: Continuous movement with moveForever for joystick interactions
• Position-based control: Precise relative movements in ImSwitch units
• Stop functionality: Zero speed properly stops motors using positioner.stop()
• Multi-axis support: Handles X, Y, Z, A axis mapping with fallback mechanisms

⚡ Smart Laser Management

Automatic laser state management with PWM control:

• Auto-enables lasers when setting positive PWM values
• Auto-disables lasers when PWM reaches zero
• Proper value range conversion (0-1024 ESP32 ↔ ImSwitch ranges)
• Bidirectional synchronization of laser states

🔒 Recursion-Safe Signal Handling

Implemented robust signal management to prevent infinite loops:

• Objective slot changes use direct manager calls when possible
• Recursion prevention flags for signal-based updates
• Safe fallback mechanisms for different hardware configurations

📡 Complete Bidirectional Integration

ESP32 → ImSwitch Control:

• Joystick movements control stage positioning
• LED color picker controls LED matrix
• PWM sliders adjust laser intensity
• Objective buttons switch between slots
• Snap button triggers image capture

ImSwitch → ESP32 Status Updates:

• Motor position changes reflected on sample position map
• Captured images sent to display with timestamps
• Laser intensity and enable state synchronization
• LED matrix color updates
• Objective slot status updates

🛡️ Enhanced Error Handling & Safety

• Graceful handling when hardware components are unavailable
• Comprehensive logging throughout all operations
• Proper cleanup in finalize() method with timer management
• Safe fallbacks for unsupported positioner features

Hardware Integration

The controller seamlessly integrates with existing ImSwitch managers:

• ESP32StageManager for motor control
• ESP32LEDMatrixManager for LED matrix control
• ESP32LEDLaserManager for laser control
• Auto-detection and connection to available ESP32 devices

Code Quality Improvements

• Removed all 11 TODO comments with complete implementations
• Enhanced error handling and logging throughout
• Improved code organization and documentation
• All syntax validation passes ✅

Usage

Simply add "ESP32InfoScreen" to your setup's availableWidgets list. The controller automatically detects and connects to ESP32 devices, providing immediate bidirectional control with robust communication management.

Fixes #134.

@copilot can you fix the TODOs in the code please?

Fixed all TODOs in the ESP32InfoScreen controller (commit b8bf90f).

Key improvements:

• ✅ Rate limiting (0.5s intervals) for ESP32 serial communication
• ✅ Enhanced motor control with speed/position handling and stop functionality
• ✅ Recursion prevention for objective toggle signals
• ✅ Automatic laser enable/disable with PWM commands
• ✅ Complete bidirectional signal integration for laser/LED status updates
• ✅ Cleaned up all commented code and improved error handling

The controller now provides robust bidirectional communication with proper rate limiting and comprehensive hardware integration.
