* feat(mac): unified Liquid Glass pairing approval panel
Replace the serial node/device pairing NSAlerts with one floating
approval panel. Both prompters feed request cards into a shared
PairingApprovalCenter; each card shows a hardware icon, platform and
model, app/core version, source IP, a copyable short id, request age,
a trust line (first connection / already-paired-id caution / repair
token rotation), and a friendly access summary with an elevated
warning for system.run-class commands. Requests resolved elsewhere
disappear live; Not Now snoozes without resolving (gateway TTL
applies) and the menu-bar pending line reopens the panel. Liquid
Glass surface on macOS 26+, material fallback on macOS 15. Deletes
the NSAlert + invisible-host-window machinery, dead node isRepair
handling, and text-only describe() body.
Closes#102535
* fix(mac): satisfy swiftformat conditionalAssignment and resync native i18n inventory
* fix(gateway): stop device pairing approval alert floods from retrying devices
A device retrying with a broken token minted a new pending requestId (and
approval alert broadcast) every 5-minute TTL window because refresh preserved
ts and expiry keyed on ts. Pending requests now stay alive via an internal
refreshedAtMs keepalive (ts still owns ordering/--latest), superseded device
requests broadcast device.pair.resolved like node pairing already did, and the
Mac app keeps one alert per device, closes superseded visible alerts, and
resyncs its queue when approving a stale request.
Closes#100974
* chore: satisfy swiftformat and refresh native i18n inventory for pairing prompter changes
