chore(release): v1.28.41 — complete the translations, guard the gap

illness.vital.FUNCTIONAL_IMPACT (the recovery-driver track that wins ties
in the illness insights card's driver selection) was referenced but absent
from all six locale bundles, rendering its raw dotted key on a live
surface — the same dynamic-key seam that let the WHO-5/SCI reminder labels
ship untranslated. Added the label in de/en/es/fr/it/pl.

Closed the class structurally: a new enum-driven
dynamic-key-exhaustiveness test imports the source enum/const for each
high-value dynamic key space (illness scan types + functional-impact,
illness type/lifecycle, allergy + family-relationship records enums, the
mental-health instrument slugs — the WHO-5/SCI seam) and asserts every
member's built key resolves non-empty in all six locales, so a missing
translation fails CI instead of reaching a user. Fallback-protected spaces
(Strava raw sport_type) and structurally-unreachable keys are documented
as excluded. Removed one confirmed-orphan key (illness.vital.SKIN_TEMPERATURE,
zero call sites).
