UI fixes: header height, map color, panel scroll

- MainNavigation: fixed min-height to prevent jumping on mode switch
- CatalogMap: default pointColor changed from green to orange (#f97316)
- CatalogPage: panel scroll on entire container, not inner
- SelectionPanel: sticky header and search, removed inner scroll
