Refactor: Improve preference migration and build script variables

The preference migration logic in `Migration.kt` has been enhanced to support wildcard matching for keys, allowing for more flexible cleanup of related preferences (e.g., `APP_ALIAS_*`). The migration now runs for versions between the saved and current version codes, inclusive. Additional logging has been added to provide detailed insight into which keys are removed during the process.

In `app/build.gradle.kts`, the `versionCodeBase` variable has been renamed to `baseVersionCode` for clarity. The `app_version` string resource in the `debug` build type now correctly uses the `baseVersionCode` instead of the `baseVersionName`.
