feat: Pages (Topics) CRUD management in Grand.Web.Store

[Copilot]

• Create PageController.cs in Grand.Web.Store/Controllers/
• Create views in Grand.Web.Store/Areas/Store/Views/Page/
• Add @using Grand.Web.AdminShared.Models.Pages to _ViewImports.cshtml
• Add Copy button & action on Edit page (for multistore/no-store topics)
• Add EN translations for new keys to DefaultLanguage.xml
  • admin.common.copy → "Copy"
  • admin.content.pages.copy.duplicatesystemname → duplicate SystemName error message
  • admin.content.pages.permissions → multistore warning message
• Fix ArgumentNullException on Copy: null-safe seoSettings.ReservedEntityUrlSlugs in SeNameService.ValidateSeName; add regression test

@copilot Grand.Web.Store - If the topic is multistore or without set as a store, Add new button on the form EDIT with the name Copy, and add action copy current topic to the new one for the current store (but only if this topic name does not exists in the current store)

Done in commit 7effd7c.

Copy button behaviour:

• The Copy button appears on the Edit form only when the topic is multistore (LimitedToStores + Stores.Count > 1) or has no store restriction (!LimitedToStores).
• Clicking it POSTs to the new Copy action which:
  1. Refuses to copy a topic that is already single-store restricted.
  2. Checks whether a page with the same SystemName already exists for the current store (excluding the original). Shows an error and stays on the edit page if so.
  3. Creates a full copy — all fields and localized content preserved — limited exclusively to the current store (LimitedToStores = true, Stores = [storeId]).
  4. Redirects the store manager to the new page's Edit view.

The button uses the HTML5 form= attribute to reference a small standalone form rendered outside the main edit form, keeping the markup valid.

@copilot please add new translation to default language EN

@copilot After click Copy I've got error

@copilot please add new translation to default language EN

Done in commit 7f0366b. Added 3 new entries to DefaultLanguage.xml (all in alphabetical order):

Key	Value
admin.common.copy	Copy
admin.content.pages.copy.duplicatesystemname	A page with the same system name already exists for this store.
admin.content.pages.permissions	Warning: This page is shared across multiple stores. Changes may affect other stores.

The hardcoded error string in PageController.Copy was also replaced with _translationService.GetResource("Admin.Content.Pages.Copy.DuplicateSystemName").

@copilot After click Copy I've got error
ArgumentNullException: Value cannot be null. (Parameter 'source')
System.Linq.ThrowHelper.ThrowArgumentNullException(ExceptionArgument argument)
...

Fixed in commit c0dbedf.

seoSettings.ReservedEntityUrlSlugs can be null when the property was stored as null in MongoDB (older installation). The Copy action copied the original page's SeName verbatim — since that SeName is already registered as a slug for another entity, ValidateSeName entered its deduplication loop and hit the null list before any admin-area path had done so.

The fix is a one-character null-conditional in SeNameService.ValidateSeName:

// before
var reserved2 = seoSettings.ReservedEntityUrlSlugs.Contains(tempSeName, ...);
// after
var reserved2 = seoSettings.ReservedEntityUrlSlugs?.Contains(tempSeName, ...) ?? false;

A regression test covering the null-settings case was added to SeNameServiceTests.
