Add POS order booking modal and utilities with tests:

- Introduced `PosDesktopOrderBookingSelectorModal.vue` to streamline booking selection for desktop POS.
- Added `orderBookingDisplay.js` utility for handling booking display and reference value normalization.
- Created unit test `select-vehicle-form-pos.spec.js` to validate booking selection flow and registration matching.
- Implemented `run-playwright-ci-parallel.mjs` script to optimize Playwright CI with parallel testing.
- Updated styles and responsiveness for enhanced booking modal UX.
