PM_K-1 hardware: tag parts into circuit-block "sheets" for KiCad select-by-block

Browse source 
board.py now wraps each section in a SKiDL Group (Power/MCU/Audio/RTC/MIDI/Indicator/
Speaker/Interconnect) via inline grp()/endgrp() helpers (no reindent). The netlist now
carries a per-part (sheetpath (names "/<block>/")), so in Pcbnew you can right-click a
footprint -> Select -> Items in Same Hierarchical Sheet and move a whole block at once
instead of dragging 167 loose parts. 167 parts across 8 sheets; ERC 0 errors.
