Use Node.js script for Cronicle trigger to avoid shell dependency

Switches from curl (shell not available in Cronicle container) to a Node.js
inline script using the built-in http module. Tries raggr-green first, falls
back to raggr-blue automatically — no manual update needed on color swap.

Delete the existing broken Cronicle event before redeploying.
