feat(team): public Team page + HQ CMS panel

New "Team" section — a LinkedIn-style minimal profile page for the FLUX
team, fully editable from the HQ Command Center.

Data model:
- New TeamMember model (name, role, bio, photoUrl, optional social links:
  email/linkedin/x/website, order, isActive, translationsJson).
- Additive migration 20260602120000_add_team_member (IF NOT EXISTS guards).
- Name stays as written; role + bio are translatable via the AI engine.

HQ panel (/hq-command/dashboard/team):
- Drag-to-reorder (same HTML5 pattern as the Hero panel).
- Inline auto-save for name/role/visibility; expandable editor for photo
  upload, bio, social links, and AI auto-translate to IT/VEC/ES/DE.
- Photo upload reuses /api/assets with a new flat "team" scope -> /public/team/.
- Dashboard tile added.

Public page (/[locale]/team):
- Responsive card grid (framer-motion stagger), portrait + name + role +
  bio + social icons (only the links that exist render).
- Per-member Person JSON-LD + breadcrumb for SEO.
- Localized via getLocalizedData; new TeamPage namespace in all 5 locales.
- NavBar item "Team" inserted before "Spare Parts" (translated 5 locales).
- Added to sitemap.

Infra:
- "team" scope registered in /api/assets (SCOPE_ROOTS + FLAT_SCOPES +
  buildPublicUrl) and revalidate.ts (RevalidateScope + path).
- Nginx serves /team/ from disk; docker-compose mounts public/team in both
  app and nginx (rw + ro).

Verified: production build compiles, all 5 /[locale]/team routes + the HQ
panel render; TypeScript clean; 5 message files valid JSON.
