First, does the MCU of classic and Pico Espruino board have a Unique Device ID? ...and if so: Second, how would I get a hold of the Unique Device ID in Javascript?

Yes, they do - process.env.SERIAL and also getSerial() contain the unique ID.

If there are other chip-specific things you want it's actually pretty easy to find the address from the datasheet and use peek to pull the data out...
