refactor(fe): viewport-fit zero-scroll layout for 11 pages (Part 2)

## Summary
- BatchOperationsPageV2: add overflow-y: auto (ShadowRunQueue, DataQualityPage)
- ModelsList: add flex:1 + min-height:0 + overflow-y:auto
- ShadowRunList: change height to 100% (from calc(100vh - 210px))
- ModelOperationsPage: add overflow-y: auto
- WbsWorkspacePage: add flex:1 + min-height:0 + overflow-y:auto
- IngestionStatus, CommonCodeManagementPage: already fitted (via component inheritance)
- MarketDataIngestion: already fitted (EditFormPage)
- HomePage, RebalanceForm, UiStandardPage: already fitted (earlier session)

Total: 11 pages viewport-fit, 7 pages already compliant

Still needed:
- ModelDetail, ShadowRunDetail: need PageLayout wrapping or refactoring
