frontend: fix onboarding bounce, mobile sidebar btn, notif deep-links, analysis header

- Fix clinic onboarding loop: refresh session after setActive before navigating,
  surface setActive errors, and guard AppAuthGuard's onboarding redirect race (#1)
- Add a mobile-only floating top-right SidebarTrigger so the sidebar is reachable
  when the offcanvas sidebar is closed on phones (#5)
- Make notifications clickable: navigate to the source (conversation/patient) and
  mark read; MessagesView/PatientsView honor ?conversation= / ?file= deep links (#6)
- Analysis page: add an Overview header with a time-range segmented control and a
  Customize popover that shows/hides sections; range slices month-based charts (#10)
