feat(soldados): Nostr social (zaps, follows, ranking) + newsletter CRM proxy

[agustinkassis]

Summary

Adds a set of Nostr-native social features to the soldiers pages, plus a newsletter signup proxy. Built across this session.

Note: this branch also carries the earlier perf(badges): instant skeleton + ~4-5x faster relay fetch commit (537bab5), which had no PR yet.

Soldados — Nostr social

• Zaps (NIP-57) — per-soldier zap button: pick amount + message, auto-pay via WebLN when present, otherwise show a BOLT11 QR + copy fallback. Falls back to a plain LNURL-pay (with comment) for any valid lightning address, not only ones that advertise NIP-57.
• Live "Zaps recibidos" wall — real-time kind-9735 subscription showing sender (name/avatar) + message + amount.
• Follow / unfollow (NIP-02) — button with status (Siguiendo / Te sigue / Se siguen), hover → red Dejar de seguir, and a styled confirm dialog with the user's avatar. Available on the profile, grid and table views via a batched follows provider (one relay round-trip for all rows).
• Grid cards — social-style Nostr banner cover behind the avatar; incomplete profiles (missing name/avatar) sort to the end; softened cursor-tracking glare.
• Admin "Recrear ranking" — recomputes the ranking from all sources (curated PROJECTS + reports.json + Nostr submissions), publishes it as a server-signed (LACRYPTA_NSEC) kind-30078 replaceable snapshot, server-caches it, and renders snapshot + newer Nostr submissions merged on top. Button is admin-gated (NEXT_PUBLIC_LACRYPTA_ADMIN_NPUB).

Newsletter

• POST /api/events-subscribe — server-only proxy to La Crypta's CRM subscribe endpoint (EVENTS_SUBSCRIBE_URL / EVENTS_SUBSCRIBE_LISTS); reworked NewsletterCTA to use it.

Architecture notes

• Official ranking event mirrors the existing reports/badges pattern: admin signs a kind-27235 authorization request → server validates + counter-signs with LACRYPTA_NSEC → publishes → revalidateTag. Read via lib/nostrSoldiersCache.ts ("use cache", static-null fallback to live compute).
• No new required env vars (reuses LACRYPTA_NSEC, NEXT_PUBLIC_LACRYPTA_ADMIN_NPUB, REVALIDATE_SECRET).

Verification

• pnpm exec tsc --noEmit clean.
• /soldados renders 200 via the snapshot → live-fallback pipeline (no snapshot published yet).
• /api/soldiers/ranking rejects unauthorized requests (400 missing request, 401 bad signature); admin/publisher pubkeys configured and distinct.
• Zap modal discovers the lightning address and generates a real invoice; LNURL-pay fallback returns a valid BOLT11.
• Follow confirm dialog + admin button render only in their intended states (verified in-browser with a simulated admin session).
• A real ranking publish was not triggered (would write La Crypta's official event to public relays with the production key).
