Fix Lite auto-refresh silently skipping every tick (#824), rename CPUs to Logical CPUs (#825)

The timer tick handler set _isRefreshing = true before calling RefreshAllDataAsync,
which also checked _isRefreshing and returned immediately — every auto-refresh was a no-op.
Removed the redundant guard from the tick handler so RefreshAllDataAsync owns the flag.

Renamed "CPUs" to "Logical CPUs" in the FinOps server inventory tab (both Dashboard and Lite)
to clarify the relationship with the Cores/Socket column, which shows physical cores.
