feat(website): partner application form on /partners

Replace the bare partner CTA with a "Become a partner" section: a pitch
column (with a secondary "book a partner call" link to /demo) plus an
application form — name, company, work email, website, partnership type
(reseller / white-label / not sure) and message. On submit it composes a
prefilled email to info@dezky.eu (interim, no backend), to be swapped for
a real intake/CRM later. Bilingual and responsive.
