[Feature] UI: Add archive action to StatusesPage (admin-only)

[mpaulosky]

Summary

StatusesPage.razor shows a grid with Edit actions but has no way to archive or delete a status. Once the API endpoint exists (see #121), this UI work adds the archive action — admin-only, with confirmation.

Context

Mirrors the Categories archive UI work (see #122). The page uses RadzenDataGrid with inline edit; the action column currently has only an Edit button.

Work Required

Archive Button

• Add an "Archive" button to the action column — visible only to admins (AuthorizeView Policy="Admin")
• Wire to HandleArchive(string id) method

Confirmation Dialog

• Use the existing ConfirmDialog component before submitting
• Text: "Archive '[StatusName]'? Issues with this status will need to be reassigned."

API Call + Feedback

• Call StatusApiClient.ArchiveAsync(id) (add this method to the client)
• On success: remove the row from the grid (optimistic UI)
• On failure: show error notification

Acceptance Criteria

• Archive button visible to admins only
• Confirmation dialog shown before archiving
• Confirmed archive calls DELETE API and removes item from grid
• Non-admin users cannot trigger the action
• Error state handled

Files

• src/Web/Components/Features/Statuses/StatusesPage.razor
• src/Web/Components/Features/Statuses/StatusApiClient.cs

Depends On

• [Feature] API: Add DeleteStatus handler and archive endpoint #121 (API: Add DeleteStatus handler and archive endpoint)
