* Add ownership checks to global task endpoints
- Restrict GET /api/tasks and POST /api/tasks/stop/{task_id} to admin-only
- Add new scoped POST /api/tasks/chat/{chat_id}/stop endpoint with ownership
check so regular users can stop their own chat tasks
- Allow admins to access the scoped chat task endpoints alongside owners
- Update frontend to use the new scoped stop endpoint when a chatId is available

* Handle temporary (local:) chat IDs in scoped task endpoints
Temporary chats use local:<socketId> as chat_id which doesn't exist in
the DB. The scoped endpoints now skip ownership checks for local: IDs
(they aren't enumerable) and use {chat_id:path} to handle the colon in
the URL path.

* Verify session ownership for local: chat IDs and URL-encode chat_id
- For local:<socketId> chat IDs, look up the socket's owner in
SESSION_POOL and verify it matches the requesting user (or admin)
- URL-encode chat_id in frontend fetch calls to handle special
characters (colon in local: IDs) safely

The chatCompletionEventHandler runs getMessageContentParts() and
removeAllDetails() on every streaming token to extract sentences
for real-time TTS dispatch via CustomEvent('chat'). These functions
perform multiple O(n) regex passes over the full accumulated message
content, resulting in O(n^2) total work over a streaming response.
The only consumer of these events is CallOverlay.svelte, which is
only mounted when showCallOverlay is true. Without the overlay open,
the parsing runs but the dispatched events have no listeners.
Wrap all three TTS parsing blocks in an if () guard
so the expensive regex work is skipped entirely for the vast majority
of users who are not using the voice call feature.
