fix: resolve duplicate Vue instance SSR crash from reka-ui peer dep conflict

- Add .npmrc with shamefully-hoist=true to prevent pnpm from creating
  isolated Vue module instances for each package
- Upgrade @nuxt/ui from 4.4.0 to 4.6.0 (uses reka-ui 2.9.2 vs 2.7.0)
- Add pnpm.overrides to pin Vue and reka-ui to consistent versions
- Fixes "Cannot read properties of null (reading 'ce')" SSR 500 error
  caused by reka-ui ConfigProvider using a separate @vue/runtime-core
  instance from the server renderer
