Seed UNS hierarchy across 6 sites; rebrand outputs to SCADA IT/OT with ZB template

Lands per-site UNS subtree files (Warsaw West/North, Shannon, Galway, TMT,
Ponce) seeded from OpenText facility docs — Warsaw split confirmed as
numbered = legacy Zimmer = West, lettered = legacy Biomet = North. Renames
project framing from "Shopfloor IT/OT" to "SCADA IT/OT" for accuracy.
Extracts a ZB-branded PowerPoint template from example_powerpoint.pptx and
wires it into the outputs pipeline. Trims deck from 18 to 16 slides
(BOBJ->Power BI transferred to another team, Non-Goals and Asks dropped);
goal-state BOBJ analysis pruned to a stub.
