feat: Configure Room schema for WidgetDatabase

Added the Room schema definition for the `WidgetDatabase` and configured the KSP arguments to export it.

This change introduces the initial schema (version 1) for the `widgets` table, which will store widget placement and sizing information. The schema location is now set in the `app/build.gradle.kts` file.
