feat(mental-health): rebuild the check-in page around four instrument cards

The landing slims to intro + instrument cards: the combined history card
leaves the main page entirely. Each card body now opens a per-instrument
detail sheet (the med-/Vorsorge card interaction) carrying the last
score + band, the score-over-time trend chart (restored from the
pre-v1.27.6 chart, lazy Recharts, bands surfacing discreetly in the
tooltip), the dated result history with the crisis re-surface, the Start
action, and the instrument's required attribution line — the Verlauf is
deliberately opt-in behind a click, never pushed onto the page someone
arrives at to take stock.

The wizard drives from the registry: option values in source order (the
WHO-5 leads with 5 = all of the time, the SCI with 4), shared vs
per-item anchor groups, and recall-stem captions above the WHO-5 / SCI
item fragments. WHO-5 items and anchors ship VERBATIM from the official
WHO publication in all six locales; the SCI is validated in English, so
every non-English locale presents the English items plus a localized
'validated in English' note (a self-made translation would invalidate
the instrument — the leak-guard allowlist documents this as intended).
Result view: direction-aware follow-up hints (WHO-5 <= 50 points gently
to the PHQ-9 check-in; SCI <= 16 carries the paper's neutral band
wording; PHQ-9 / GAD-7 keep their >= 10 hint). The intro states each
recall window honestly (two weeks vs past month). The Vorsorge screening
group offers all four instruments. Chrome localized in de/en/es/fr/it/pl.
