feat: port cms contact layout into trade-pro (info/form/no-fake-submit)

Task 10f. contact.html rebuilt from contact.astro + LeadForm.astro:
PageHero (breadcrumb/cover bg) -> 0.85/1.25 info+form-card grid ->
rich body section (body only). No-fake-submit dual form: configured
HTTPS form_endpoint renders external form (name/email/message +
pro-honeypot, 10b contract); unconfigured renders no <form> at all,
guidance card with real mailto when footer_email exists. Contact
items render only with real fields (email mailto; no fabricated
phone/address), cms map band dropped (no address data source).
CSS appended to pro.css with own 900/620 media blocks; new test
test_trade_pro_contact_layout_structure covers both shapes.
