chore: drop tooling and host references from templates and comments

- The translation issue template called eight locales "AI-initial",
  left Russian out of its list and its dropdown; it now says they
  started as machine-translated drafts reviewed by the community.
- The pull request template asked for two locales where the checks
  require all ten, and pointed at an ignored docs folder.
- Code comments named the maintainer notes file, a release by its
  working name and an internal host; old changelog entries explained
  the notes files by their tool-specific names. A fixture token and
  the deploy webhook test's application id (a real one) are replaced.

+        HealthLog ships German and English as maintainer-curated translations. French, Spanish, Italian, Polish, Korean, Dutch, Brazilian Portuguese and Russian started as machine-translated first drafts and are reviewed by the community. They pass the locale-integrity test (full key parity, no empty values), but not every line has been read by a native speaker for register or regional vocabulary.
 
         This template captures concrete fixes you would like to see. Phrasing nuance, regional vocabulary (e.g. "Tú" vs "Usted"), gendered forms, and domain-specific health terms are all in scope. The maintainer applies fixes during the regular release cycle.
