ESP32 Wi-Fi STA Connection (with LCD Screen)

In this project, we connect the ESP32 to the home Wi-Fi network in Station (STA) mode in a secure, fault-tolerant manner. We store the SSID and password in a separate `secrets.h` file to prevent leaking to Git, set up an auto-reconnect mechanism, and display the RSSI signal level and IP address on an I2C LCD screen. The internal LED works as a status indicator. It is a production-grade connection manager.
