Zoltan Papp 2bd56ecf67 [client/ui] Remove goroutine from ProfileSwitcher.SwitchActive
Down and Up(async=true) are both fast RPCs; no background goroutine
is needed. SwitchActive is now fully synchronous — the tray wraps the
call in its own goroutine, and Wails handles React calls similarly.

// ProfileSwitcher encapsulates the full profile-switching reconnect policy so
// both the tray and the React frontend use identical logic.
//
// Reconnect policy:
//
// ┌─────────────────┬──────────────────────┬────────────────────────────────────┐
// │ Previous status │ Action │ Rationale │
// ├─────────────────┼──────────────────────┼────────────────────────────────────┤
// │ Connected │ Switch + Down + Up │ Reconnect with the new profile. │
// │ Connecting │ Switch + Down + Up │ Stop old retry loop, restart. │
// │ NeedsLogin │ Switch + Down │ Clear stale error; user logs in. │
// │ LoginFailed │ Switch + Down │ Clear stale error; user logs in. │
// │ SessionExpired │ Switch + Down │ Clear stale error; user logs in. │
// │ Idle │ Switch only │ User chose offline; don't connect. │
