feat(ui): show dashboard version in the header

Operators had no way to see which Node Manager version their node is running.
/api/nodes now returns `ui_version` (the UI bundle version constant the updater
gates on), and the header sub-title renders it as "Network Operations · v<x.y.z>"
— visible on every tab, on both the SSH-tunnel and public dashboards.

UI_VERSION 1.8.1 -> 1.8.2. Ran tools/gen-checksums.sh per AGENTS.md.
