Follow-up to #3797. The inbox:new handler keys the notification-preference
query on item.workspace_id, but the request itself still resolved its
workspace from the active-workspace X-Workspace-Slug header. On a cold
cache, a user viewing workspace B who received a workspace-A notification
read B's mute setting and cached it under A's key — so A's banners could
fire while muted (and vice-versa), polluting A's cache.
Add an optional workspaceSlug override to getNotificationPreferences and
notificationPreferenceOptions, and pass the resolved source slug from the
inbox:new handler. When the source slug can't be resolved, read only an
already-warm cache instead of fetching with the wrong workspace. Tests
cover the cold-cache source-slug fetch, source mute suppression, and the
no-fallback guard.

Users can now mute specific notification categories (assignments, status
changes, comments & mentions, priority/due-date updates, agent activity)
from Settings > Notifications. Muted event types are silently filtered at
notification creation time — no inbox items are created for muted groups.

- Add GET/PUT /api/notification-preferences endpoints
