fix(content): German register breaks, stale disclaimer comments, safety-floor wording

Three German strings broke register: the doctor-report wellness
disclaimer and the Sie-register clinician view's attachment hint both
leaked a du-form word into otherwise neutral/Sie text handed to a
clinician, and the sharing settings' "shownOnce" hint used a Sie
imperative inside the app's own du-form settings surface. All three
now match the register their surface actually uses.

daily.line.allClear ("everything's tracking normally") edged toward an
all-clear verdict the safety-floor module deliberately never makes;
drops the second clause to match the already-existing, safer
daily.today.allClear wording, across all six locales.

Four insights explainers (fat mass, visceral fat, daylight, falls)
asserted health-outcome links with no citation while their siblings
(resting HR, pulse wave velocity, VO2 max) all cite a named guideline
body inline; adds the same parenthetical anchor to each.

Two coach-panel comments still described a per-page "always visible"
clinical-decisions disclaimer that DISC-01 (v1.18.6) replaced with the
one-time onboarding acknowledgment — the code was already correct, the
comments were stale and now say so.
