Description

This PR may fix #2933 and provides the events for web UI being able to react on favourite events (as also reported in opencloud-eu/web#3016

Enhancement: Send SSE events when items are added to or removed from favourites

Currently, marking or unmarking a resource as a favourite does not notify connected web clients, so favourite state changes made in one browser tab or on another device only becomes visible after a manual reload. The graph service already published LabelAdded/LabelRemoved events on the event bus for this; the clientlog service now also consumes them and forwards item-favorite-added/item-favorite-removed SSE notifications to the affected user, mirroring how renames and moves are already announced.
