Delete legacy v1 frontend (resources/scripts)

The resources/scripts/ directory was the original Vue 2 / Pinia v1 admin and customer-portal SPA. It has been fully orphaned for some time — vite.config.js has zero entry points pointing at it and the only blade @vite() reference in resources/views/app.blade.php loads scripts-v2/main.ts. The directory was pure dead code.

Removes 424 .vue / .js / store / router / helper files (~2.7 MB) so that resources/scripts-v2/ can be renamed back to resources/scripts/ in a follow-up commit, dropping the v2 suffix now that there is no v1 left.
