feat: i18n, language switcher fix, DataTable improvements, blade translations

- Translation system: lang/es/ PHP files (auth, validation, pagination, passwords)
- Rappasoft vendor translations published (lang/vendor/livewire-tables/es/)
- JSON files synced to 391 keys (EN + ES, full parity)
- APP_LOCALE changed to 'es', users.locale column default changed to 'es'
- Language switcher fixed: JS event + window.location.reload() avoids /livewire/update redirect
- SetLocale middleware fallback uses config('app.locale') instead of hardcoded 'en'
- setSortingPillsEnabled(false) on ProjectTable, CompanyTable, UserTable
- Translated 17 blade views: project-map, template-manager, layer-manager,
  company-management, phase-list, media-manager, reports-dashboard,
  client-projects, layer-upload, project-form, project-map-editor-tab,
  admin/users, projects/media, projects/templates, layouts/client
- Navigation 'Empresas' link uses __('Companies')
- Fixed typo key 'Fases and layers' -> 'Phases and layers'
