NexaPay purge: VYNDR is Stripe-only — remove all NexaPay traces

NexaPay was cross-project contamination (from another venture) — never a real VYNDR payment path. Purged; Stripe path untouched. Removed: - web/src/services/nexapay.ts (createPaymentLink/getTransaction/HMAC verify) - web/src/app/api/webhook/nexapay/route.ts (the only importer; Next-registered, reachable — now gone) - NexaPay comments in email.ts + checkout/route.ts - Active NexaPay entries in docs/SYSTEM-MANIFEST.md (route list, NEXAPAY_* env table, service row) + stale claim in wiring-data-train.md - sw.js precache entry for the deleted webhook chunk Verified: ZERO NexaPay in code (web/src, src, tests). Full suite 3833 green (count unchanged — nothing depended on it, confirming it was dead). Web build exit 0. sw.js parses clean. Stripe checkout untouched (Next→Express→Stripe). FLAGGED FOR KEV (a repo delete cannot close these): - Coolify env: remove NEXAPAY_API_KEY / NEXAPAY_WEBHOOK_SECRET / NEXAPAY_API_URL - Revoke the NexaPay API key + webhook secret at NexaPay's dashboard; de-register the webhook if an account was ever configured - DB column user_profiles.nexapay_customer_id is orphaned (no reader/writer) — drop via a follow-up migration (migration 011 left as history) Cross-project check: ZERO Noctem-Supabase refs; VYNDR references only its own Supabase (zmdnczhtdxcddsxzttub). NexaPay was the sole contamination found. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VsztNChZ7vEvSR61AuMhD1

 ### 1a. Billing "RENEWS 6/9/2036" — ✅ fixable
 - **Render:** `web/src/app/profile/page.tsx:128` renders `subscription_end` verbatim from the Supabase `user_profiles` row. Honest render, bad data — no hardcoded 2036 in source.
- **Root cause:** the live web payment path is **NexaPay, not Stripe**. `web/src/app/api/webhook/nexapay/route.ts:41-50` writes `subscription_end = now + 30 days` (a synthetic guess). The 2036 value is a **manually-seeded/comped founder-account row** the UI trusts blindly. The *real* Stripe `current_period_end` exists at `GET /api/stripe/status` (`stripeService.js:278`) but the UI never consumes it.
- **Task:** point the "Renews" stat at a provider-asserted value (consume `/api/stripe/status.current_period_end`, or have the NexaPay webhook persist its real next-bill timestamp instead of now+30); correct/clear the stale 2036 row. Guard: never render a `subscription_end` the provider didn't assert → fall back to `—`.
+- **Root cause (UPDATED 2026-07-27 — NexaPay purged):** VYNDR is Stripe-only. The old note pointed at a `web/src/app/api/webhook/nexapay/route.ts` that wrote `subscription_end = now + 30 days` — that webhook was cross-project contamination and has been DELETED. The 2036 value is a **manually-seeded/comped founder-account row** the UI trusts blindly. The *real* Stripe `current_period_end` exists at `GET /api/stripe/status` (`stripeService.js:278`) but the UI never consumes it.

 ### 1b. James Wood → "Chicago Cubs" / builds vs AL East — ✅ fixable (nameKey collision)
 - **Root cause:** `mlbStatsAdapter.js:192` `people.find(p => nameKey(p.fullName) === targetKey)` returns the **first** exact-nameKey match with **no namesake disambiguation**. A second "James Wood" in the statsapi season list (a Cubs-affiliate namesake) wins → wrong `currentTeam`. The S59 substring guard only covered *fuzzy* mismatches; it never covered two players sharing an exact name — **not a regression**, an uncovered case.
