[client] Always connect on profile selection except in manage profiles (#6838)

Selecting a profile from the header dropdown or the tray submenu now
always brings the connection up after the switch, regardless of the
previous daemon state. Switching from the manage-profiles screen
(including profile creation) never connects, leaving a chance to adjust
the management URL first.

## Summary by CodeRabbit

* **New Features**
* Added the ability to switch profiles without automatically
establishing a connection.
* Existing profile switching continues to connect when appropriate,
while safely handling active or pending connections during the switch.
