Sp 1494 api integration (#180)

* SP-1494-api-integration.

* fixed left stide titles intervals in total energy consumption chart.

* Adjusted tooltip and title intervals in energy management charts to improve accuracy by incrementing displayed values by one.

* Refactor AnalyticsCommunitiesSidebar to use AnalyticsSpaceTreeView and enhance community/space selection handling

* Gave every tab its own selection logic using the strategy design pattern, along with clearing the selection when changing tabes to avoid collision between features.
