fix: resolve session switching failure when same-named sessions exist on different devices

The sidebar click guard, active highlight, mobile bottom sheet, and kill-session
auto-close all compared sessions by name only, ignoring remoteId. This caused
same-named sessions on different devices to be treated as identical — clicking
one while viewing the other was silently discarded as a no-op.

Now all 6 comparison sites check both name AND remoteId, using the _viewingRemoteId
that was already being tracked but never used in guards.

Bumps version to 0.4.4.
