Replaced static `Application` references with instance-based `App` context across the codebase. Updated calls to `Application.RequestStop()` and `Application.Screen` to use `App?.RequestStop()` and `App?.Screen` for better encapsulation and flexibility. Refactored test infrastructure to align with the new context, including reintroducing `FakeApplicationFactory` and `FakeApplicationLifecycle` for testing purposes. Improved logging, error handling, and test clarity by adding `logWriter` support and simplifying test setup. Removed redundant or obsolete code, such as `NetSequences` and the old `FakeApplicationFactory` implementation. Updated documentation to reflect the new `IApplication.RequestStop()` usage.
