style(detail): apply gradient header strip to client/interest/yacht/company/berth/residential/invoice details

Adds shared <DetailHeaderStrip> wrapper (rounded-xl + gradient-brand-soft + shadow-xs)
and applies it to every legacy domain detail header. Residential client/interest and
invoice detail get an inline gradient strip with eyebrow ('Residential Client',
'Residential Interest', 'Invoice'). Residential bodies normalized to lg:grid-cols-[2fr_1fr]
per spec.
