feat(mobile): ios widgets (#19148)

* feat: working widgets

* chore/feat: cleaned up API, added album picker to random widget

* album filtering for requests

* check album and throw if not found

* fix app IDs and project configuration

* switch to repository/service model for updating widgets

* fix: remove home widget import

* revert info.plist formatting changes

* ran swift-format on widget code

* more formatting changes (this time run from xcode)

* show memory on widget picker snapshot

* fix: dart changes from code review

* fix: swift code review changes (not including task groups)

* fix: use task groups to run image retrievals concurrently, get rid of do catch in favor of if let

* chore: cleanup widget service in dart app

* chore: format swift

* fix: remove comma

why does xcode not freak out over this >:(

* switch to preview size for thumbnail

* chore: cropped large image

* fix: properly resize widgets so we dont OOM

* fix: set app group on logout

happens on first install

* fix: stupid app ids

* fix: revert back to thumbnail

we are hitting OOM exceptions due to resizing, once we have on-the-fly resizing on server this can be upgraded

* fix: more memory efficient resizing method, remove extraneous resize commands from API call

* fix: random widget use 12 entries instead of 24 to save memory

* fix: modify duration of entries to 20 minutes and only generate 10 at a time to avoid OOM

* feat: toggle to show album name on random widget

* Podfile lock
