Marc-André Bombeck 3c4bbdef4f feat(i18n): MaintainershipBanner notice + foundation for 4 new locales
Add the four AI-initial locale bundles (FR / ES / IT / PL) and a
small dismissible MaintainershipBanner strip that paints at the top
of the auth shell whenever the active locale falls outside the
maintainer-curated set (currently DE + EN). The banner names the
AI-initial provenance and links to a GitHub translation-feedback
template so users can contribute fixes back. Dismissal persists
per-locale in localStorage so dismissing the FR banner does not
hide the IT banner once the user switches language.

The bundles are generated by scripts/i18n/build-locale.py — a layered
walk of messages/en.json that applies a vocabulary lookup keyed on
the lowercase EN value, preserves every {interpolation} placeholder
and <tag> marker verbatim, and falls through to the English value
for long-tail prose the script can't translate. The banner advertises
this status so users know what they are looking at. All four locale
files pass the i18n-locale-integrity test verbatim — full key
parity to en.json, no empty values, no TODO/FIXME placeholders,
no value-equals-last-segment matches.

Foundation work bundled with the banner so the build never lands in
a half-wired state:
- locales array extended to ["de","en","fr","es","it","pl"] with
  matching localeLabels + MAINTAINED_LOCALES set + isMaintainedLocale
  helper in src/lib/i18n/config.ts.
- INTL_LOCALE_MAP and parseLocaleFromAcceptLanguage in
  format-locale.ts gained the four new tags so SSR locale resolution
  and Intl number/date formatting work end-to-end.
- i18n/context.tsx and i18n/server-translator.ts import the four new
  JSON bundles alongside DE + EN.
- Coach (src/lib/ai/coach/system-prompt.ts) and the strict insights
  generator (src/lib/ai/prompts/insight-generator.ts) ship the EN
  system prompt with a one-line REPLY LANGUAGE footer for the four
  AI-initial locales. The DE branch keeps its hand-curated body
  verbatim. Routing through the EN system prompt preserves every
  safety contract (zero hallucinations, no dose-prescription,
  evidence-block sentinel format) without re-validating four new
  language bodies.
- Five locale-parameter signatures (no-key-fallbacks, glp1-plateau,
  time-window-format, target-prompts, medication-form) widened
  from "de" | "en" to the canonical Locale type. Helpers that
  ship DE+EN copy route non-DE locales to the EN body, mirroring
  the same fallback chain the JSON bundles use.
- OpenGraph alternateLocale on the root layout lists the four new
  BCP-47 tags so social-link previews advertise the broader
  language coverage.

Tests:
- 4 new SSR tests pin the locale gate (EN/DE hidden, FR/ES/IT/PL
  visible by default, dismissed flag honoured) and the re-exported
  isMaintainedLocale helper.
- parseLocaleFromAcceptLanguage gains a FR/ES/IT/PL coverage block
  alongside the existing DE / EN / unknown branches.
- The existing i18n-locale-integrity suite auto-discovers each new
  messages/<locale>.json and runs the 25-sub-test parity + value-
  quality battery against it — all six locales pass.

LocalePicker is data-driven (settings and onboarding both iterate
the locales array) so promoting the array to 6 entries grows both
dropdowns without per-call-site changes. The PDF doctor-report
renderer is t()-driven for every label, so the four new JSON
bundles give that renderer FR/ES/IT/PL output without touching
doctor-report-pdf-core.ts.
