feat(copy): reposition as Endorphin research desk, de-emphasize AI

Shift sitewide voice from "AI-scored signal tool" to "Endorphin — a crypto
research desk with a real edge". AI drops to the methods layer; "public +
timestamped calls" becomes the credibility/viral hook.

- layout.tsx: new tagline ("signals that move price before the crowd"),
  description rewritten (drops "scored by AI"); Organization JSON-LD is now
  Endorphin with Trump Alpha as its brand; SoftwareApplication gains
  publisher/author → #org; metadata creator/publisher → Endorphin.
- [locale]/page.tsx: home title "Live Crypto Signal Desk" + new description.
- DashboardClient.tsx: hero subtitle rewritten with viral hook.
- methodology intro: prepend Endorphin "research project not a marketing
  funnel" line; keep the "live production logic" credibility line.
- [locale]/layout.tsx footer: "© Trump Alpha — a research project by Endorphin".
- llms.txt + opengraph-image: synced to the same positioning (per CLAUDE.md).

tsc clean, next build passes. Functional names (Macro Vibes/KOL/6 engines)
unchanged to avoid SEO/llms.txt drift. No trading/API/component changes.
