split monitors tab and surface boot type and nic link state

Tracked Services and Tracked Processes were sharing a tab with system health cards, so what is running on the box and how the box itself is doing read as one list. They now sit in a Service/Process Monitors tab and the old tab is System Monitors. The group vocabulary is duplicated across the renderer, the tab map and the panel declarations with nothing checking they agree, and a group named in one but not the others is dropped in silence - that has eaten cards twice. Tests now pin the vocabulary on both sides. Boot type and NIC link state were collected in Phase 2 but shown nowhere. Boot type only renders when fast startup applies, because uptime measured from a resume understates how long the kernel has been up and that is the case worth naming. Link state leaves a disconnected NIC unknown rather than half duplex: live hardware returns empty speed and duplex when unplugged, and half duplex is the cable fault signature this column exists to catch.
