docs: clarify llms.txt and llms-full.txt behavior with authentication

[mintlify-development]

Summary

Documents the new auth-aware behavior for llms.txt and llms-full.txt so users know what is served on fully and partially authenticated sites.

Changes

• Replaced the generic authentication note on ai/llmstxt with the new behavior: fully authenticated sites return 404 for /llms.txt and /llms-full.txt (authenticated users can still fetch an llms.txt scoped to their permissions), and partially authenticated sites serve both files publicly with only public pages and no OpenAPI/AsyncAPI specification links.
• Updated the Feature availability table in deploy/authentication-setup to reflect the same split.
• Mirrored both updates into the Spanish, French, and Chinese translations.

Context

Reflects the user-facing effects of these source PRs:

• Partial-auth support for llms.txt (filters to public pages, returns 404 when no public pages exist).
• Hiding OpenAPI/AsyncAPI specs from llms.txt on auth deployments.
• Auth-aware llms-full.txt (skipped for fully-authed sites, public-only filter for partially-authed sites).
• New authenticated llms.txt endpoint for fully-authed deployments that excludes hidden pages, pages restricted to user groups, and spec URLs.

---

Note

Low Risk
Low risk documentation-only change that clarifies how llms.txt/llms-full.txt are served on fully vs partially authenticated sites; no product logic is modified.

Overview
Clarifies in ai/llmstxt.mdx that authentication behavior for llms.txt/llms-full.txt now differs between fully authenticated sites (unauthenticated requests get 404, authenticated users can fetch a permission-scoped llms.txt) and partially authenticated sites (files are public but include only public pages and exclude group-restricted/hidden pages and OpenAPI/AsyncAPI spec links).

Updates the Feature availability table in deploy/authentication-setup.mdx to match, and mirrors the same documentation updates across the Spanish, French, and Chinese translations.
