webui: per-source status bar in FRU/Elabel card + fix stale runtime-health test

Show an explicit per-source status line after "Read All" instead of hiding
failed/blocked sources in a "(skipped: …)" tail. Sources blocked by a missing
Supermicro license (SFT-OOB-LIC / SFT-DCMS-SINGLE) are flagged in red with an
actionable message, so engineers see that SAA DMI is gated rather than silently
falling back to the futile ipmitool FRU path (BIOS re-syncs FRU from DMI on boot).

Also fix TestDashboardRendersRuntimeHealthTable, stale since 4f6579e moved
"inactive" to the OK service states: the fixture now uses a failed service and
the assertion matches the current contract (failed flagged, inactive not).
