fix(frontend): restore @vue/cli-service v5, remove PostCSS config files

Root cause: commit 6a4d0496 downgraded @vue/cli-service to v4 and
added postcss:^8.4.49 as a direct dependency, causing remove-scoped.js
(Cannot read properties of undefined (reading 'spaces')) crash.

Fix:
- @vue/cli-service ^4.5.19 -> ^5.0.9
- copy-webpack-plugin ^5.1.2 -> ^14.0.0
- Remove .postcssrc.js, postcss.config.js, vue.config.js
- Remove postcss from dependencies (v5 brings its own)
- Remove postcss/postcss-selector-parser from overrides
