Vendored from https://github.com/gpeter62/ESP_UniClock: the sketch source, the web UI and the libraries the ESP8266 build needs, unpacked from the bundled zips. Adds a PlatformIO project for the ESP-12. The source is unchanged; local changes follow as separate commits. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
