The same "is this post in the user's current workspace?" check was
duplicated across every Post-related endpoint (5 in Api/PostController
via the ensurePostInCurrentWorkspace helper, 5 in App/PostController
inline). PostPolicy already had a duplicate() method following this
exact pattern — extending it with view/update/delete unifies the
tenancy guard in one place.
- Add view/update/delete to PostPolicy. Each returns
Response::denyAsNotFound() when the post belongs to a different
workspace, so we keep the existing 404 behavior (don't leak
cross-tenant existence) instead of switching to the default 403.
- Update duplicate() to also use denyAsNotFound() for the workspace
mismatch path. The createPost role check still returns bool/403.
- Replace ensurePostInCurrentWorkspace() calls in Api/PostController
with $this->authorize('view'|'update'|'delete', $post). Helper deleted.
- Replace inline workspace_id !== $workspace->id checks in
App/PostController (show/edit/update/destroy/platformMetrics) with
the same authorize calls. The PostPolicy guard now subsumes both
the workspace-tenancy check and the role-permission check that was
previously delegated through Workspace::createPost.
