Chore: Finalize English translations, review categories, and move demo languages before release

[andrewbrazzatti]

Background

We added several non-English language files for demo purposes. Before the release we need the English translations to be complete and authoritative, validate the metadata/category structure, and relocate demo languages so only production-ready locales remain.

Tasks

• Audit English translations: verify every key in meta.json exists and is correct in translation.json. Fix missing keys, incorrect placeholders, and pluralization inconsistencies.
• Review categories & descriptions: review category groupings and description fields in meta.json. Propose and document any re-categorizations or description edits.
• Move demo languages: identify non-production language folders under language-defaults (those added for demo) and move them to [language-defaults/demo/]. Update i18n loading if needed.
• Add verification: (optional) add a small CI or local check that fails when a key in meta.json is missing from the English translation.
• Create PR: include the fixes, a short changelog, and a runbook for future translation updates.

Acceptance criteria

• All keys in meta.json are present (and correctly formatted) in translation.json.
• meta.json categories and descriptions have been reviewed and changes are documented in the PR.
• Demo language folders are moved to [language-defaults/demo/], and the codebase builds or CI runs without new i18n regressions.
• PR includes summary of changes, verification steps, and any needed follow-ups (e.g., translators to contact).

Files to review

• meta.json
• translation.json
• Non-English folders under language-defaults (to be moved into [language-defaults/demo/])

As part of this task, or separate related tasks, there are a few places that English text is directly in code. This text should be extracted to the language file and replaced with a translation helper and the key.

Look in both the angular apps and the server-side libraries for text to extract.
