fix: align startup copy with 2026 founding and deploy hybrid rendering

- Replace fabricated 12-year/500+/8+ team experience claims with
  2026 founding, first-client co-creation, professional team wording
- Remove fake case studies and unverified certifications from seeds,
  cases page, products and ERP upgrade page
- Enable Next.js standalone output and production hybrid deployment
  (Dockerfile.prod, docker-compose.server.yml, Nginx nextjs upstream)
- Add linux-musl Prisma engine target and production crypto key build
- Sync production CMS database with cleaned seed content
