Fix TypeScript type declarations and bump version to 1.0.1-beta.4

- Remove nested declare module wrapper from logger.d.ts to fix double-nesting issue
- Add types field to package.json
- Update version to 1.0.1-beta.4
- Update IOR identifier to com.metatrom.universal-components.logger@1.0.1-beta.4

This fixes TypeScript import errors where the Rollup IOR plugin was wrapping
already-wrapped types, causing a nested module structure that prevented proper imports.
