* feat(cli): add `issue subscriber` commands
Wrap the existing /subscribers, /subscribe, and /unsubscribe endpoints as
`multica issue subscriber list|add|remove`, mirroring the comment subcommand
shape. `--user <name>` reuses resolveAssignee to resolve a member or agent;
without the flag, the action targets the caller.
* fix(issues): default subscribe target to resolveActor, not X-User-ID
When no user_id is posted, subscribe/unsubscribe hardcoded the target as
("member", X-User-ID). A CLI caller running as an agent (X-Agent-ID set)
then subscribed the underlying member rather than the agent itself,
which contradicts the "defaults to the caller" contract.
Derive the default via resolveActor so the endpoint mirrors caller
identity consistently — agent caller → agent row, member caller →
member row. Adds a regression test covering the agent caller path.
* fix(server): validate workspace membership for subscription targets and file uploads
Closes MED-1 (cross-workspace subscription injection) and MED-2 (file upload
missing workspace member validation) from the security audit.

* test(server): add negative tests for cross-workspace subscription and upload
Address PR review feedback:
- Add tests verifying cross-workspace user_id is rejected with 403 on
subscribe and unsubscribe
- Add test verifying upload with foreign workspace_id is rejected with 403
- Make isWorkspaceEntity explicitly enumerate "member"/"agent" and reject
unknown user types

Replace inbox_listeners.go with a subscriber-driven notification system:
- Add issue_subscriber table with auto-subscribe on create/assign/comment
- New subscriber_listeners.go: maintains subscriber data on domain events
- New notification_listeners.go: notifySubscribers (fanout to all subscribers
minus actor) and notifyDirect (targeted, punches through unsubscribe)
- Subscriber API: list/subscribe/unsubscribe endpoints
- Frontend: subscribers section in issue detail sidebar with real-time sync
- Frontend: inbox notification grouping by (issue_id, type, actor_id)
- Remove createInboxForIssueCreator from task.go (unified through event bus)
- 21 new Go tests, all passing
