9c move Non-IO grouping policy from core stats/types into dashboard

Snapshot.NonIOFamilies, Snapshot.NonIOFamiliesCount, and
types.IsNonIOSyscallFamily encoded a TUI tab concept in core packages.
Move this filtering into internal/tui/dashboard/nonio.go as unexported
helpers so the dashboard owns its own grouping policy and
Snapshot.Families remains the neutral core API.
