mangavalkandClaude Opus 5.5 b347f1c63f Import ESP_UniClock (upstream 1189810)
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.
