feat(acl): server endpoints + client + UI for circle membership
Round-trip out a long-standing hole in the ACL feature: until
this commit a circle on Yavsc was an empty named bucket. You
could create 'Famille' and grant it on a post, but the circle
carried no members, so 'Famille' authorised no one. The MVC
admin controller (Yavsc.Org.Controllers.CircleMembersController)
existed but had no REST counterpart, so PostIt — which only
talks to the Yavsc.Blogs API — had no way to manage membership
at all.

This commit closes that gap end-to-end:

Server (Yavsc.Blogs)
- GET    /api/circle/{id}/members           list members
- POST   /api/circle/{id}/members           add a user (body { userId })
- DELETE /api/circle/{id}/members/{userId}  remove a user
  All three are scoped to caller == circle.OwnerId; non-owned
  circles return 404 (not 403) to avoid leaking existence, in
  line with the rest of the controller.
- Two new DTOs (CircleMemberDto, AddCircleMemberDto) for the
  wire shapes. CircleMemberDto mirrors UserSearchResultDto
  minus Email — membership UI doesn't need contact details.

Tests (Yavsc.Blogs.Tests)
- CircleMembersApiTests: 5 [Fact] covering empty list,
  add+get, duplicate add → 409, remove, and cross-owner 404.
  Test users (alice, bob) are seeded directly through the
  in-memory DbContext — the Blogs fixture doesn't stand up
  UserManager<ApplicationUser>.

Client (Yavsc.Api.Client)
- CircleMemberDto + 3 methods on CircleApiClient:
  GetMembersAsync, AddMemberAsync, RemoveMemberAsync.
  All match the server's contract: 404 flattens to null,
  409 surfaces as an exception (callers can dedupe beforehand
  if they want idempotent behaviour).

UI (PostIt)
- CirclesPageViewModel gains a Members ObservableCollection
  that auto-loads on SelectedCircle change (via the partial
  setter generated by [ObservableProperty]). Commands:
  LoadMembersAsync, OpenAddMember (raises an event the view
  subscribes to), OnAddMemberConfirmedAsync (called by the
  view when the dialog confirms a selection), RemoveMemberAsync.
  409 (already a member) is detected from the exception
  message and surfaced as a friendly status rather than an
  error — a likely race when the same user gets added twice
  through two UI paths.

- CirclesPage layout is now two-pane (circles + editor on the
  left, members of the selected circle on the right). The
  member pane has an 'Ajouter un membre' button that opens
  AddCircleMemberDialog. Code-behind wires the dialog's
  Confirmed event back into the VM via an async lambda
  wrapper (EventHandler<T> wants void, the VM method is
  async Task).

- AddCircleMemberDialog is a ContentPage (light modal, same
  pattern as PostAclDialog). Its ViewModel consumes
  IUserDirectory — the abstraction introduced by 04a31709
  to fix the 'user search should not be IContactService'
  confusion. The dialog raises Confirmed with the picked
  UserSummary; the host (CirclesPage) is responsible for
  calling CircleApiClient.AddMemberAsync.

Out of scope (tracked in MEMORY.md, 2026-08-18):
- i18n: all visible text still hard-coded French.
- XAML accessibility audit of pre-existing pages.
- Avalonia.Headless UI tests of the new navigation flow.

Tests: 51/51 PostIt.Tests green, 20/20 Yavsc.Blogs.Tests
green (was 15; +5 for CircleMembersApiTests), 44/44
Yavsc.Org.Tests green (no regression).
