Various tweaks (#381)

* Add the message delivery status to the plain timeline styler and display it outside of the main content

* Fix glitchy timeline scroll to bottom button

* Fix the sliding sync cold cache: treat invalidated rooms as filled

* Make splash screen view full screen

* Fix the offline indicator popping up when first setting up the network monitor

* Expose presentationDetents on the NavigationStackCoordinator and start using them for the EmojiPicker

* Fix link tint color

* Linked TimelineReactionsView reaction sending

* Remove now unused/unnecessary classes

* Add changelog

* Fix formatting issue
