Add note editing and deletion capabilities

[Copilot]

Notes attached to posts were immutable once created. This adds full CRUD support for notes.

Changes

API endpoints (NoteEnpoints.cs)

• GET /api/notes/note/{rowKey} - Retrieve note by ID
• PUT /api/notes/note - Update note
• DELETE /api/notes/note/{rowKey} - Delete note

Data layer (DataStorageService.cs)

• GetNote() - Query note by RowKey from Azure Table Storage
• DeleteNote() - Remove note entity from storage
• Existing CreateNote() already handles upsert via UpdateEntity check

Client (PostNoteClient.cs)

• Added GetNote(), UpdateNote(), DeleteNote() methods wrapping API calls

Domain (NoteDialogResult.cs)

• New result class to handle dialog responses with action type (Save/Delete) and note data

UI

• NoteDialog.razor - Enhanced existing dialog to support both create and edit modes
  • Detects edit mode based on note's RowKey
  • Shows Delete button only when editing existing notes
  • Returns NoteDialogResult indicating action type
• Posts.razor - NoteEdit button (📝) now opens dialog with existing note data
  • Handles both Save and Delete actions from dialog
  • Uses pattern matching for type-safe result handling

Tests (NoteEndpointsTests.cs)

• Coverage for GET/PUT/DELETE endpoints with valid/invalid inputs
• Verification of note deletion cascades properly

// Posts page button opens dialog for editing
<FluentButton OnClick="@(() => EditNoteForPost(context!.NoteId))" 
              IconEnd="@(new Icons.Filled.Size20.NoteEdit())" />

// Opens existing NoteDialog in edit mode
private async Task EditNoteForPost(string noteId)
{
    var existingNote = await client.GetNote(noteId);
    var dialog = await DialogService.ShowDialogAsync<NoteDialog>(existingNote, ...);
    // Handle Save or Delete action
}

This section details on the original issue you should resolve

<issue_title>Edit and Delete Notes on a post</issue_title>
<issue_description>We should be able to edit an existing note on a post.
And We should be able to delete a note.

I think the best way would be that from the post list use the EditNote button.
The delete button could be implemented in the edit not form.

Don't forget to add unit tests to validate it all works.</issue_description>

@copilot in term of functionality this is exactly what we need.
However you created a entire new noteeditor, could we instead reuse the one that exist as dialog src/NoteBookmark.BlazorApp/Components/Shared/NoteDialog.razor ?

We could just modify that on to support editing too instead of duplicating code.

Refactored to reuse the existing NoteDialog.razor component for both creating and editing notes. The dialog now:

• Detects edit mode automatically based on note's RowKey
• Shows a Delete button only when editing
• Returns a NoteDialogResult to indicate the action (Save/Delete)

Removed the redundant NoteEditor.razor page. All functionality is now handled through the dialog, maintaining consistency with the existing UX pattern.
