📄 Description

Describe your changes

Fixes the GUI client sometimes not connecting for a long time after SSO login —
until the user interacts with the app (e.g. hovering the tray icon).

Root cause: the login flow orchestrates Login → WaitSSOLogin → Up in the
frontend (client/ui/frontend/src/lib/connection.ts). WaitSSOLogin blocks in
the daemon while the user completes SSO in the external browser. During that
time the tray window is hidden and the webview is suspended (macOS App Nap /
Windows hidden-window timer throttling), so the promise continuation that
issues Up doesn't run until the webview resumes — which only happens on user
interaction. This is exactly the stall client/ui/frontend/src/lib/stallwatch.ts
was added to detect in #6717 ("the WaitSSOLogin → Up handoff"); that PR added
detection only.

Fix: move the handoff off the webview's critical path. A new Go method
Connection.WaitSSOLoginAndUp performs WaitSSOLogin and then Up entirely in
Go, so the daemon connects the moment SSO completes, independent of webview
state. The frontend calls this single method on the SSO path and no longer
issues its own Up; the non-SSO (token) path is unchanged. Cancellation still
works via the bound call's context cancel, and the method re-checks ctx.Err()
before Up. The UI catches up via the status subscription when the window
wakes.

client/ui/services/connection.go: add WaitSSOLoginAndUp
client/ui/frontend/src/lib/connection.ts: use it on the SSO path; drop the
separate frontend Up there

Checklist

Is it a bug fix
Is a typo/documentation fix
Is a feature enhancement
It is a refactor
Created tests that fail without the change (if possible)
This change does not modify the public API, gRPC protocols, functionality behavior, CLI / service flags, or introduce a new feature — OR I have discussed it with the NetBird team beforehand (link the issue / Slack thread in the description). See CONTRIBUTING.md.

By submitting this pull request, you confirm that you have read and agree to the terms of the Contributor License Agreement.

Note: this adds a UI-service method consumed only by the bundled desktop
frontend (not a public/gRPC/CLI surface). No behavior change outside the GUI
login path. Hard to cover with an automated test — it is webview-suspension
timing behind an external SSO round-trip; verified by manual repro (log in,
leave the tray window hidden, confirm the tunnel comes up without interaction).

Summary by CodeRabbit

New Features
- Added a streamlined connection flow that waits for SSO authentication to complete before bringing the connection online.
- After success, the authenticated email address is returned as part of the connection process.
Bug Fixes
- Improved handling of canceled requests by ensuring interruption is detected after SSO completes.
- Authentication and connection failures now surface as clearer, more consistent errors.
