feat(tenant): enforce English output for en-US template generation

Browse Source 
When the article locale is en-US, Chinese prompt templates could leak
Chinese wording into generated titles, outlines, and article bodies.
Add high-priority language-consistency guards so the model treats the
Chinese template text as internal instructions and emits English only.

- Append per-artifact locale guards (analyze/title/outline) in template
  assist prompts and an article-body guard in the generation prompt,
  only when locale is en-US
- Reinforce locale consistency in the title/outline runtime prompts and
  drop retained images from the rewrite prompt
- Cover the new guards with unit tests
