feat(ui): show per-inbound live speed (#5261)

* feat(utils): add speedFormat utility and tests

* feat(inbounds): add InboundSpeedEntry type

* feat(inbounds): add speed column to inbound list

* feat(inbounds): show speed in inbound stats modal

* feat(inbounds): compute inbound speed from traffic deltas

* feat(inbounds): wire inbound speed through page

* feat(i18n): add speed translation for all locales

* refactor(inbounds): dedupe live-speed UI and harden formatting

Extract a shared InboundSpeedTag component and isActiveSpeed guard used by the speed column and stats modal, unify InboundSpeedEntry into a single type, and route speedFormat through sizeFormat.

Also guard sizeFormat against non-finite input (no more "NaN PB/s") and clear stale per-inbound speeds when a traffic poll returns no deltas.
