refactor: move UI and test modules to core namespace

- Relocate `:ui:shared` module to `:core:ui`.
- Relocate `:ui:test` multiplatform test framework to `:core:test-ui`.
- Relocate `:ui:test-jvm` testing utilities to `:core:test-jvm`.
- Update `settings.gradle.kts` to reflect the new project structure.
- Adjust project dependencies in `app/android`, `app/desktop`, `app/web`, and `app/ios-kit` build files.
- Update generated resource package references from `notedelight.ui.shared` to `notedelight.core.ui`.
- Update documentation, architecture guides, and README files to reflect new module paths and names.
