The Ignore <-> Unignore context-menu entry was driven by
avatarInfo.isIgnored — a boolean captured by AvatarInfoUtilities once,
at the time the avatar was clicked. If the user got ignored / unignored
*while the popup was already open* (e.g. via the friends panel, or
because a server push flipped the state), the menu kept showing the
stale option and clicking it would no-op (or worse, double-ignore).
Switch the menu items to read useIsUserIgnored(avatarInfo.name) — the
reactive hook backed by IgnoredUsersManager.getIgnoredUsersSnapshot()
+ NitroEventType.IGNORED_USERS_UPDATED. Now the menu flips automatically
the moment the ignore list changes, without re-opening.
avatarInfo.isIgnored stays on the data object (other code paths still
consume it) — only the user-facing menu toggle is now reactive.
