fix: remove fabricated marketing content, replace with honest new-agency framing

Testimonials, case studies, a fake personal work history, inflated company
stats, per-service metrics, blog posts, tech-stack proficiency percentages,
and SEO meta/JSON-LD (including a false 2017 foundingDate) all invented
content that never existed. Replaced with real dated milestones, honest
empty-states ("new agency, real results coming soon"), and only verifiable
facts about what Aura has actually built and shipped.
