One-shot prettier pass so the new format:check gate starts from a clean
baseline. Formatting only — no behaviour change. Generator-owned and
vendored artifacts stay untouched via .prettierignore.
Regenerate `docs/api/openapi.yaml` so the `InsightsLayoutBody` enum
carries the canonical English tile ids first, then the
accepted-but-deprecated legacy German ids, with the normalisation +
deprecation spelled out in the schema description. Add ADR 0001 fixing
the convention — localised UI copy, English internal identifiers — and
the non-breaking alias strategy. Add an iOS coordination note covering
the new canonical ids, the continued acceptance of the legacy ids, and
the recommended migration path.
