Cloud: bugfixes: log refresh errors and allow logout from inactive-session

[jr]

This UI is potentially too minimal, but there's a bit of a compromise: inactive-session isn't an error 100% of the time, but you do need to be able to get out of it.

Important

Add handling for inactive sessions and update UI to reflect authentication state in AuthService, CloudService, and AccountView.

• Behavior:
  • Add inactive-session event to AuthService in AuthService.ts to handle transitions to inactive session state.
  • Log errors during session refresh in AuthService.ts.
  • Update CloudService.ts to listen for inactive-session events.
• UI:
  • Update AccountView in AccountView.tsx to show login/logout buttons based on cloudIsAuthenticated state.
  • Add cloudIsAuthenticated to ExtensionState in ExtensionStateContext.tsx and update related components.
• Tests:
  • Update ClineProvider.test.ts and ExtensionStateContext.test.tsx to test new authentication state handling.
