Fix RGBW management for FastLED (ESP32-C2,C3,C5,C6,S3) and SPI LEDs for others

[awawa-dev]

Fixed a critical issue where SK6812 RGBW LEDs failed to render correctly on platforms using FastLED (ESP32-C2, C3, C5, C6, and S3). The fix addresses flawed RGB-to-RGBW memory workarounds by enforcing correct 4-byte data alignment within the library's native 3-byte structure, ensuring stable and accurate color output for these specific hardware targets.

Added a new button to the Network settings section to reset SSID/Password and force a switch to AP mode.

Fixed a critical bug in SPI initialization when using the NeoPixelBus library across ESP32, ESP32-S2, ESP8266, and Pico platforms. Additionally, all supported platforms underwent a comprehensive review specifically to ensure stable and correct support for APA102/DotStar LEDs.

Every driver has been verified through a full round of physical testing, and with this hardware validation complete, the project is now transitioning to the Beta phase.

Details:

• Fix RGBW management: Resolved FastLED RGBW issues for ESP32-C2, C3, C5, C6, S3 boards
• Fix SPI LEDs: Correct initialization of SPI drivers for Pico, ESP32, ESP32-S2, and ESP8266
• Fix Default GPIOs: Corrected SPI defaults for ESP8266, ESP32-S2, ESP32-S3, Pico, and ESP32-C6
• Rendering update: Changed NeoPixelBus Neopixel rendering methods for ESP32
• Pico Support: Enforced mandatory restart on Pico boards after LED configuration changes
• ESP32-ETH01: Fixed SPI LED stability and rendering
• Update recently added boards: Added FastLED SPI LEDs support for ESP32-C2 and ESP32-C5
• Network UI: Added button to reset WiFi credentials and switch to AP mode
