feat(supply): per-unit fit-out/cost-bearer/MAB/parking with object fallback (resolveUnitFacts)

- unit: add fitOutByLandlord, mieterausbaubeitragPerSqm, parkingSpots (parking = allocation from object pool)
- lib/unitFacts.resolveUnitFacts: single resolver (unit value ?? object value) used by scorer + card adapter
- matchSyncService: pre-market unit scored via resolved facts (fit-out, MAB, cost-bearer, parking allocation)
- matchCardAdapter: fit-out label/viability/investment via resolveUnitFacts
- UnitStructurePanel: consolidate ALL per-unit overrides into the one expandable row editor (price, availability, Ausbaustandard, Wer-baut-aus, MAB, parking allocation); show parking on row
- PreMarketUnitGrid/Panel: drop the duplicate per-unit fit-out select (now in the unit editor)
