Christian Byrne 1df6187972 [ci] add stylelint dependency and minimal config (#5926) ...

## Summary

Adds [stylelint](https://stylelint.io/) configuration and tooling to
enforce CSS/SCSS code quality and consistency across Vue components.

Starts with 21 focused rules for linting CSS in Vue SFC files and
standalone stylesheets. Configuration uses postcss-html to parse Vue
`<style>` blocks and includes whitelists for Tailwind v4 at-rules
(`@reference`, `@plugin`, `@custom-variant`, `@utility`) and
Electron-specific CSS properties (`speak: none`, `app-region`). Rules
emphasize modern CSS syntax (numeric font weights, modern color
functions, double-colon pseudo-elements) while avoiding overly
opinionated rules like hex color length enforcement (for now).

Currently finds 113 issues (79% auto-fixable). This PR only adds the
tooling via `pnpm stylelint` and `pnpm stylelint:fix` scripts - no
pre-commit hooks or CI integration yet. A follow-up PR will auto-fix the
fixable issues and optionally add enforcement to the commit workflow.

## Changes

- **What**: Integrated [stylelint](https://stylelint.io/) with Vue.js
support via postcss-html parser
- **Dependencies**: Added `stylelint@16.24.0`, `postcss-html@1.8.0`

## Review Focus

CSS rule strictness and Tailwind CSS compatibility - particularly the
`no-descending-specificity` rule and Tailwind-specific function ignores.
