feat: improve English UI and ACE filament mapping

Complete English-mode coverage for browser-visible UI strings and console messages.

Extract uploaded G-code/3MF filament metadata and use it to build smarter ACE/AMS slot mappings while preserving existing fallback behavior.

Ignore local config and Codex workspace files generated during development.
