Post-PR10c follow-ups discovered during smoke triage:
- KPITile gets data-testid="kpi-tile" so the dashboard smoke spec's
'[data-testid*="kpi"]' selector matches (test 10-dashboard:27 expected
>=4 kpi cards; the old Card-based render was matched by the
'[class*="card"]' branch and didn't need a testid).
- Residential interest detail eyebrow text reverted from "Residential
Interest" to "Residential interest" (lowercase i). The visual is
identical because the wrapper has the `uppercase` class; the smoke
spec at 26-residential:140 looks for the literal lowercase string.
