One lesson-level supplementary-media entry (EXP-029 / MED-05).
Mirrors a media.yaml resource minus domain (inherited
from the parent set). Surfaced in the "Vertiefe das Thema"
section after the lesson summary. Optional + additive, so
pre-EXP-029 lessons load unchanged. Added to the authoritative
schema (EXP-039) so the JSON-Schema / generated TS types cover
it — previously this shape lived only in the frontend
ContentLessonResource interface, and a lesson carrying
resources was rejected by extra="forbid" here.
