ML-44 Save zoom level for equipment profile (#164)

* made zoom slider vertical & added more ticks to ruler

* show sliders values

* increased slider tappable area

* more accurate sliders values

* added zoom slider to equipment profiles settings

* split `EquipmentListTiles` widget

* set zoom on equipment profile change

* clamp zoom to the nearest value

* added missing translations

* added zoom checks to e2e test

* removed unused import
