chore(build): adopt Vite, pnpm, ESLint flat config; drop Vue CLI

Replaces Vue CLI 4 with Vite 7 + @tailwindcss/vite + vite-plugin-pwa,
yarn with pnpm, tslint with ESLint 9 flat config, and Jest with Vitest.
Drops Netlify deploy config and the dead FontAwesome npm token.

Bumps the entire dependency surface: Vue 3.5, Pinia 2, vue-router 4,
vue-i18n 11, Tailwind 4, DaisyUI 5, TypeScript 5.7, axios 1.x,
mapbox-gl 3.x, date-fns 4.x, uuid 11.x, pouchdb-browser 9.x.
