fix: permissions and room icon resolution (#2)

* Initialize call state upon room creation for call rooms, remove subsequent useless permission

* handle case of missing call permissions

* use call icon for room item summary when room is call room

* replace previous icon src resolution function with a more robust approach

* replace usages of previous icon resolution function with new implementation

* fix room name not updating for a while when changed

* set up framework for room power level overrides upon room creation

* override join call permission to all members upon room creation

* fix broken usages of RoomIcon

* remove unneeded import

* remove unnecessary logic

* format with prettier
