Refactor Search flow in NGRX to fix routing

[vej-ananas]

Resolves #240

[TIL-EBP]

Some general remark:

When I start a search from the map page, then navigate to "Verrwaltung" and back to the map, the filters are closed. When I do the same via Benutzerverwaltung, the filters are open (as they should be IMO) This probably still has something to do with the portals which are still used in the "Verwatltungs"-Tab??

Nitpick: When hiding the results table, navigating away and back to map, the table is now open again. previously, this state was persisted

When I search by polygon and then reset the polygon ("Polygon aufheben") it takes much longer fot the search result to disappear than before. When going vis "Suche zurücksetzen", it is (still) almost instant

Not directly part of your PR, but i notived that when selecting an asset, navigatng to a different page and then navigtaing back to the map page, the asset is still selected, but the map zoom is not on focussed on this asset but the entire map. What is the desired behaviour there?

This still exists: Nitpick: When hiding the results table, navigating away and back to map, the table is now open again. previously, this state was persisted.

Other than that and my nitpick comments it looks good
