gui: add activeSessionPaused property for reactive paused state

The isSessionPaused() Q_INVOKABLE didn't trigger QML binding
re-evaluation on pause/resume. New property with proper signal
makes ChatPane bindings reactive.

- activeSessionPaused property tracks active session's paused state
- Updated on refreshSessions() and switchAgent()
- ChatPane.qml uses property instead of function call
