* Add the More menu to SpaceScreen.
And a simple way to leave a space for testing.
* Start a space flow when accepting a space invite from the room flow.
* Minimise the tab bar on iOS 26 when scrolling down.
* Enable spaces by default!
Make the tab bar hide when pushing screens on iPhone as requested by the designs.
Annoyingly we couldn't simply add a second call to .toolbar(.hidden, for:.tabBar) on the pushed screens, but this way is automatic and there's still an override so it's good enough for now.
* Add a SpaceExplorerFlowCoordinator.
* Project tweaks
- iOS 17.5 so that we can use the simulator.
- Make a Spaces group for common Space related views.
- Fix the tab bar badge colour on iPhone landscape and iPadOS 17 (18 is still wrong 😒)
