Fix Call buttons (tel: fallback) + replace MIT 95% stat with BCG 70%

Fix 1: Call buttons fell back to mailto: (tapping "Call" opened email) —
switch static fallback to tel:+17789856736. Display text unchanged.

Fix 2: Replace the contested MIT NANDA "95% of AI pilots fail" stat (known
methodology/COI problems) with BCG's durable 10/20/70 algorithms-tech-people
heuristic, source hyperlinked. Flows into the existing binder sentence.

-      <p>Most attempts at this quietly stall — MIT's 2025 "State of AI in Business" study found 95% of company AI projects deliver no measurable return, and the tools usually aren't the problem. Most shops have already learned it the hard way: there's a binder somewhere — half&#8209;finished, on a shelf, out of date the week it was printed. It didn't fail because the writing was bad. It failed because getting a veteran to hand over what he knows, and getting a shop to actually change how it works, is a people problem, not a paperwork one. Your best people aren't holding back to be difficult — they're protecting the thing that's made them irreplaceable for thirty years.</p>
