Point local work folders at ~/Documents/projects/sandTable-local

The KiCad working copy and the Pi image work dir moved out of ~/kicad and
~/Documents into ~/Documents/projects/sandTable-local.

 ## Notes
 - **5 V budget:** the 5 V regulator supplies 1 A. The ESP32 takes up to about 0.4 A during Wi-Fi bursts, which leaves about 0.6 A for an LED strip: roughly 10 WS2812B LEDs at full white, or more at lower brightness. On USB power alone, keep the strip off; USB gives 0.5 A in total. Use a separate 5 V supply for longer strips.
