Dashboard: fix display of flat phys fields (procedural domain)

The outer loop in DashboardTab.update assumed a 3-level hierarchy
(domain → object → fields).  Procedural fields sit one level higher
(domain → field directly).  Check _is_phys() first and render value /
unit into the correct columns instead of descending into the dict and
showing 'value' and 'unit' as separate rows.
