Miguel Beltran 0c88289339 [Compass App] Booking screen (#2380) ... This PR adds the Booking screen at the end of the main app flow. After the user selects `Activity`s, these get stored in the `ItineraryConfig` and then the user navigates to the `BookingScreen`. In the `BookingScreen`, a `Booking` is generated with the `BookingCreateComponent`. This component communicates with multiple repositories, and it is a bit more complex than the average view model, something that we want to show as discussed in the previous PRs. <details> <summary>Screenshots</summary>   </details> In the `BookingScreen`, the user can tap on "share trip" which displays the OS share sheet functionality. This uses the plugin `share_plus`, but the functionality is also wrapped in the `BookingShareComponent`, which takes a `Booking` object and creates a shareable string, then calls to the `Share.share()` method from `share_plus`. But the `share_plus` dependency is also injected into the `BookingShareComponent`, allowing us to unit test without plugin dependencies. This is an example of a shared booking to instant messaging:  **TODO** - I want to take a look at the whole experience on mobile, as I noticed some inconsistent UI and navigation issues that I couldn't see on Desktop. I will submit those in a new PR. - We also talked about user authentication in the design document. I will work on that once we are happy with the main app flow. ## Pre-launch Checklist - [x] I read the [Flutter Style Guide] _recently_, and have followed its advice. - [x] I signed the [CLA]. - [x] I read the [Contributors Guide]. - [x] I updated/added relevant documentation (doc comments with `///`). - [x] All existing and new tests are passing.
