📄 Description

Describe your changes

Users reported long delays between finishing browser SSO authentication and the client connecting. The existing logs could not attribute the time: the PKCE and device flows were silent between issuing the auth URL and returning the token, and nothing recorded when the GUI issued Up after WaitSSOLogin completed.

This adds timing log lines across the login chain:

PKCE flow: callback wait start, IdP callback arrival, token exchange duration
Device flow: polling interval, slow_down handling, approval timing (polls + elapsed)
GUI (Go side): brackets around Login, WaitSSOLogin, and Up requests
Daemon: Up RPC arrival (before the handler mutex) and WaitSSOLogin success return
Frontend: a stall detector that reports when webview timers were suspended (macOS App Nap / hidden-window throttling), which delays the WaitSSOLogin → Up handoff

Log-only change, no behavior modified.

Summary by CodeRabbit

Improvements
- Added detailed progress logging throughout device authorization, PKCE authentication, SSO login, and connection startup flows.
- Authentication logs now include polling activity, timeout and redirect details, completion status, and token exchange duration.
- Added clearer visibility into requests sent between the client and daemon without changing existing behavior.
