feat(mobile): shared album activities (#4833)

* fix(server): global activity like duplicate search

* mobile: user_circle_avatar - fallback to text icon if no profile pic available

* mobile: use favourite icon in search "your activity"

* feat(mobile): shared album activities

* mobile: align hearts with user profile icon

* styling

* replace bottom sheet with dismissible

* add auto focus to the input
