Remove duplicate root-level route groups ((public)/, (auth)/, (dashboard)/,
(admin)/, auth/) that shadowed the [locale]/ i18n-aware versions. All routes
now live exclusively under [locale]/ with next-intl middleware handling locale
detection and redirect.
- Root layout.tsx → pass-through (delegates html/body to [locale]/layout.tsx)
- [locale]/layout.tsx now imports globals.css
- Root error.tsx, not-found.tsx get html wrapper for safety fallback
- Remove redundant root loading.tsx
- 38 duplicate route files removed
