feat: Add npm dependencies and update vendor paths

- Add package.json dependencies: jquery, jquery-ui, moment, daterangepicker, wavesurfer.js, air-datepicker
- Create scripts/setup-vendor.js to copy npm packages to public/assets/vendor
- Update view templates to use vendor paths instead of old /js/ or CDN URLs
- Clean up legacy commented-out scripts in master layout
