Naiyuan Qing f85494dcf8 refactor(desktop): model pre-workspace flows as window overlays, not tab routes
Previously /workspaces/new and /invite/:id were tab routes on desktop.
That meant the TabBar rendered on top of flows that conceptually aren't
"places" the user sits at — creating a workspace or accepting an invite
is a one-shot transition, not a session. The mismatch also produced
several downstream bugs: tab state persisted these paths, the invite
deep link had no clean dispatch target, and NoAccessPage leaked TabBar
chrome when a workspace slug went stale.

Fix by recognising the underlying category mistake: on desktop, these
flows are application state, not routes. Move them to a window-level
overlay driven by a small Zustand store; the navigation adapter
intercepts pushes to the corresponding paths and routes them to the
overlay instead. Web keeps the routes (users need shareable URLs and
back-button semantics), so shared view components are reused as-is.

UX affordances (Back button when dismissable, Log out escape) live in
the shared NewWorkspacePage/InvitePage so both platforms render
identical content; the desktop overlay is now a thin platform shell
(drag strip + useImmersiveMode) that wraps the shared UX. Web wires
onBack based on whether the user has any workspaces.

Also addresses several related issues uncovered along the way:
- Logout now resets the in-memory tab + overlay stores (previously only
  localStorage was cleared, so the next login inherited the prior
  user's tabs).
- WorkspaceRouteLayout auto-heals a stale workspace slug by navigating
  to "/" instead of rendering NoAccessPage — on desktop without a URL
  bar, "no access" is always stale state, not a legitimate destination.
- IndexRedirect overlay lifecycle is bidirectional: opens when wsList
  is empty, closes when it becomes non-empty (realtime workspace:added
  would otherwise leave the overlay stuck open).
- tryRouteToOverlay resets the current tab to "/" when opening the
  new-workspace overlay; otherwise workspace-scoped components under
  the overlay continue to render and throw when the workspace they
  reference disappears from the cache (reproducible by deleting the
  last workspace from Settings).
- handleDeepLink now accepts multica://invite/<id>, IPC'd through to
  the renderer and opened as an invite overlay. Email template still
  links to https:// (unchanged), but the desktop dispatch path is now
  wired for a future "open in desktop app" bridge.
