Refactor project structure and migrate to Version Catalog

- Migrated the single `sample` module into a multi-module structure: `:sample:shared`, `:sample:android`, `:sample:ios`, `:sample:desktop`, and `:sample:web`.
- Introduced a Version Catalog (`libs.versions.toml`) to manage dependencies and plugins across the project.
- Updated Gradle to 9.3.1 and Kotlin to 2.3.10.
- Migrated library modules (`theme-material`, `theme-material3`, `theme-prefs`) to use the Android Kotlin Multiplatform library plugin.
- Added a `PUBLICATION.md` guide and updated the publication logic using `vanniktech/gradle-maven-publish-plugin`.
- Refactored `AppState` to use `TextFieldState` and updated `NoteDetailBody` in both Material 2 and 3 samples to utilize the new state and `rememberSaveable`.
- Added "Source code" and "Info" items to the settings screens with `LocalUriHandler` to link to the GitHub repository.
- Reorganized sample source code, moving platform-specific code into their respective new modules.
- Cleaned up imports and standardized `@Preview` annotations across the theme modules.
- Enabled `TYPESAFE_PROJECT_ACCESSORS` in `settings.gradle.kts`.
