Change "Only my IOC hosts" control from tab to slider so UI is consistent with other list views ICSHWI-9761

Change the "Only my IOC hosts" tab into a slider so UI is consistent with the other list views. My IOC hosts is a bit different since it has to do with which hosts you have IOCs deployed on, not which hosts you "own".

To deal with this, the slider is disabled when viewing the "Only hosts without IOCs" tab. The "own" slider is also when not logged in. The "own" controls were previously always visible when implemented as a Tab.

This merge request also touched IOCListView and JobListView to make (especially vertical) alignment of items in the tab/own grid consistent.
