add custom CSS and prop-based theming for data entry components

[minhsueh]

• Release Workflow Optimization: Integrated automated versioning for NPM. The workflow now uses npm version ${{ github.ref_name }} --no-git-tag-version to ensure the published package version strictly matches the GitHub tag/release. No longer need to have code version in project.json.

TODO:

• Added support for custom CSS and theming via component props. This allows for granular control over the visual presentation of data entry components through style.
