feat(i18n): add complete Latin American Spanish (es) UI translation catalogs

[kauenet]

Summary

• Adds complete Latin American Spanish (es) catalogs for all 3,639 UI strings across the 8 message files — including dashboard-private-channels.json (272 keys), which fr does not cover yet.
• Registers es in supportedLocales/messagesByLocale; the language picker and Accept-Language resolution (es, es-MX, es-AR, …) pick it up automatically.
• Adds the locales.es terminology block (voice, glossary-driven terminology, forbiddenTerms) to .github/translation-guidance.json, so catalog validation and the Eve release workflow enforce the conventions on every future string.

Sibling PR: #1046 (Brazilian Portuguese) — both add a locale to the same five wiring files, so whichever merges second gets a trivial rebase (supportedLocales, imports, catalog const, registry entry, guidance block are all additive).

Terminology

• Source of truth: solanabr/solana-glossary + the established fr conventions.
• Kept in English: Token, Wallet, mint/burn, allowlist/blocklist, endpoint, API Playground, Sandbox, stablecoin, on-chain/off-chain, staking, the SPL authority family (Mint/Freeze/Update/Metadata Authority, Permanent Delegate), ramp/on-ramp/off-ramp, rails, rent.
• Standard Latin American financial vocabulary elsewhere: activo, contraparte, transferencia, cotización, proveedor, custodia, custodio, decimales, cumplimiento, pago saliente (payout), fondeo (funding); tarifa for network/transaction fees vs comisión for provider fees.
• Register: tú/ustedes (never vosotros), inverted ¿ ¡. Forbidden (regex-enforced): billetera, monedero, cartera, ficha, acuñar, zona de pruebas, lista blanca/negra.

Quality process

• Terminology contract authored before translating.
• Two rounds of independent adversarial review (native register, cross-file terminology consistency, UI mechanics, meaning fidelity, and revision regression), with all confirmed findings applied.
• 100% key parity with en; placeholder tokens byte-identical; zero forbidden-term hits.

Policy

Dedicated translation-only PR per check-catalog-change-policy.mjs — zero English catalog changes.

Validation

• validateCatalogs (missing keys + placeholder parity + forbidden terms): es fully valid
• vitest src/i18n/messages.unit.test.ts (inventory parity, typed lookups, fallback): pass
• tsc --noEmit (sdp-web) — catalogs type-checked via satisfies LocalizedMessages<Messages>: pass
• pnpm test:scripts (catalog policy + release translation tooling): pass
• Biome on all changed files: clean
• Runtime: cookie and Accept-Language (es, es-MX) resolve to es; landing and dashboard surfaces render translated; en/fr unaffected.

Greptile Summary

The PR adds complete Latin American Spanish catalogs and registers the locale in the dashboard’s i18n configuration.

• Adds Spanish translations across the landing page and dashboard feature catalogs.
• Registers es for locale negotiation and typed message loading.
• Adds Spanish terminology guidance, validation rules, documentation, and locale tests.

Confidence Score: 5/5

The PR appears safe to merge, with only non-blocking Spanish terminology cleanup remaining in an existing review thread.

The previously reported removal terminology mismatch remains in the Spanish catalogs, but no blocking failure remains.
