- Extract UnitFieldsEditor (price, availability, Ausbaustandard, Wer-baut-aus, MAB, parking allocation, expected price) — single source for per-unit editing
- UnitStructurePanel: always-visible per-unit details strip (fit-out, cost-bearer, parking, expected price) in read mode; pencil opens the shared editor
- PreMarketUnitGrid: per-unit details shown + same editor reachable per unit (pencil) so fit-out/price/parking are adjustable right in the release flow
- Removes the previous edit-only / fragmented per-unit fields
