Subject: [PATCH] Calendar alternative view (#4254)

* Introduce a new view that shows all upcoming scheduled events

* remove log

* Fix unused component import that was breaking the build

* minor fix of inline style to className

* Correct PR comments

* Correct PR comments - move assignment inside className

* Alter some css colors - fix css issue that was putting the add-to-calendar button out of the box on screen resolutions more than 2000px width

* more PR comments fix - dark theme alignment
