chore(brand): scrub LibreChat brand mentions → Hanzo

Removes the upstream LibreChat brand from user-visible + internal surfaces (pt-PT
locale string, MCP trust-warning template, code comments, the libreChatProxy var,
the LIBRE_CHAT_DOCKER_TAG build-script env, README prose). App UI was already
Hanzo-branded; this cleans the residue.

KEPT deliberately:
- LICENSE / packages/data-schemas/LICENSE 'Copyright (c) … LibreChat' — the MIT
  license REQUIRES the attribution; stripping it would violate the license.
- All LibreOffice references (packages/api/src/files/documents/libreoffice.ts) —
  that is the office-suite doc-preview dependency, NOT LibreChat; removing it
  breaks document preview.
