feat: Add Storybook configuration and motion tokens implementation

- Introduced Storybook configuration files (`main.ts`, `preview.ts`, `tsconfig.json`) for Angular components.
- Created motion tokens in `motion-tokens.ts` to define durations, easing functions, and transforms.
- Developed a Storybook story for motion tokens showcasing their usage and reduced motion fallback.
- Added SCSS variables for motion durations, easing, and transforms in `_motion.scss`.
- Implemented accessibility smoke tests using Playwright and Axe for automated accessibility checks.
- Created portable and sealed bundle structures with corresponding JSON files for evidence locker.
- Added shell script for verifying notify kit determinism.
