Stefan Allius 093ec03d60 S allius/issue391 (#392)
* design counter on connection board

* display time of last update and add reload button

* chance `Updated` field to a real button

* Provide counter values for the dashboard

* change background color ot the top branch

- use dark-grey instead of black to reduce the contrast

* change color of counter tiles

* test proxy connection counter handling

* prepare conn-table and notes list building

* remove obsolete menue points

* store client mode for dashboard

* store inverters serial number for the dashboard

* store inverters serial number

* build connection table for dashboard

* add connection table to dashboard

* fix responsiveness of the tiles

* adapt unit tests

* remove test fake code

* increase test coverage, remove obsolete if statement
