倪程伟 cf5d47d249 fix(security): cross-workspace guard on isConversationOwner (#344)
Closes the authorization asymmetry between list endpoints (which filter
by workspaceId) and direct-access endpoints (which did not): a logged-in
user could reach another workspace's system / IM / webchat-owned
conversation by id and run any of messages / delete / rename / pin /
setModel / clear / chat-files download on it.

Per the maintainer's guidance on issue #344, workspaces are now treated
as untrusted isolation boundaries — the fix is the cross-cutting
hardening, kept out of feature work.

Behavior change (only for shared, non-direct convs):
- requester is a global admin (user.role=admin) → pass
- requester is a member of the conversation's workspace → pass
- otherwise → deny

Preserved to avoid regressions:
- direct owner (username == conv.username) → pass without lookup
- convs without workspace_id (legacy rows) → legacy system-owner check
- anonymous user (authService returns null, e.g. permitAll reconnect)
  → legacy system-owner check

Callers in ConversationController / ChatController / SubagentController /
GoalController / ApprovalController (18 sites) are unchanged — the
signature stays isConversationOwner(conversationId, username). The
workspace membership check is done via WorkspaceService.hasPermissionCached
(Caffeine-backed, same cache the WorkspaceAccessInterceptor uses) and
ignores the X-Workspace-Id header, which is client-controlled.

Tests: 11 cases in ConversationServiceOwnershipWorkspaceTest covering
each branch of the new logic. No caller-side test changes — the 66
caller tests (ConversationService*Test, ChatController*Test,
SubagentController*Test, GoalController*Test, ApprovalController*Test)
still pass.
