ConsoleTab was a static placeholder that showed no data. The proxy already forwarded MCP server stderr as notifications/message events, but the UI had no dedicated view for them. ConsoleTab now receives the notifications array and renders all notifications/message entries in a terminal-style panel: log levels are color-coded, the view auto-scrolls to the latest entry, and a Clear button lets users dismiss accumulated output without affecting the History/Notifications panel.

Pull request overview
This PR makes the Client “Console” tab functional by rendering MCP server stderr/logging notifications that were already being forwarded by the proxy, addressing the gap described in #1283.
Changes:
- Implement a terminal-style log viewer in
ConsoleTabthat filters and displaysnotifications/messageentries with level-based coloring, auto-scroll, and a local “Clear”. - Wire
Appstate (notifications) intoConsoleTabvia a new prop so the tab can render incoming server notifications.
