feat(mobile): Manual asset upload (#3445)

* fix: exclude albums filter in backup provider

* refactor: Separate builder methods for Top Control App Bar buttons

* fix: Show download button only for Remote only assets

* fix(mobile): Force Refresh duration is too low to trigger it consistently

* feat(mobile): Make Buttons dynamic in Home Selection DraggableScrollableSheet

* feat(mobile): Manual Asset upload

* refactor(mobile): Replace _showToast with ImmichToast calls

* refactor(mobile): home_page selectionAssetState handling

* chore(mobile): min and initial size of DraggableScrollState increased

This is to prevent the buttons in the bottom sheet getting clipped behind the 3 way navigation buttons
in the default density of Android devices

* feat(mobile): notifications for manual upload progress

* wording
