Julien	6cde0096e2	Add notifications to the web UI when configuration reload fails. This commit introduces a new `/api/v1/notifications/live` endpoint that utilizes Server-Sent Events (SSE) to stream notifications to the web UI. This is used to display alerts such as when a configuration reload has failed. I opted for SSE over WebSockets because SSE is simpler to implement and more robust for our use case. Since we only need one-way communication from the server to the client, SSE fits perfectly without the overhead of establishing and maintaining a two-way WebSocket connection. When the SSE connection fails, we go back to a classic /api/v1/notifications API endpoint. This commit also contains the required UI changes for the new Mantine UI.
