fix: enable enforce-consistent-class-order tailwind lint rule (#9428)

## Summary

Enable `better-tailwindcss/enforce-consistent-class-order` lint rule and
auto-fix all 1027 violations across 263 files. Stacked on #9427.

## Changes

- **What**: Sort Tailwind classes into consistent order via `eslint
--fix`
- Enable `enforce-consistent-class-order` as `'error'` in eslint config
- Purely cosmetic reordering — no behavioral or visual changes

## Review Focus

Mechanical auto-fix PR — all changes are class reordering only. This is
the largest diff but lowest risk since it changes no class names, only
their order.

**Stack:** #9417 → #9427 → **this PR**

Fixes #9300 (partial — 3 of 3 rules)
