improve(ui): show real machine identity in the place picker (#112162)

* improve(ui): show real machine identity in the place picker

The place picker labeled the gateway destination with a hardcoded
'Gateway · local' and let duplicate device names collide. The gateway
destination now shows the host's machine name via the existing
system.info method (falling back when unavailable), node rows carry
platform/model/IP facts as tooltips, and duplicate labels — same-named
devices and same-basename recent folders — get a deterministic muted
suffix chosen collision-only (model, then IP, then id; parent folder,
then path, then node facts for recents). IP addresses never render
inline by default. Phone-family nodes get a phone chip icon.

* fix(ui): appease prod-type and no-shadow gates in place identity helpers
