docs + fix: Leads module doc, badges onsite doc, license access fix, QR log cleanup

- Add MODULE__AE_Events_Exhibitor_Leads.md — full module reference (auth model, tabs,
  data model, routes, offline/PWA notes, OSIT admin notes)
- Add MODULE__AE_Events_Badges_Onsite.md — onsite printing guide (browser settings,
  CUPS/Linux setup, Zebra ZC10L section with test results, Epson stub, troubleshooting)
- Archive PROJECT__AE_Events_Exhibitor_Leads_v3*.md + Zebra test day doc → history/
- Fix leads license management access: ae_tab__manage.svelte license section now visible
  to administrator_access OR shared-passcode sign-in (type === 'shared'); matches spec
- Add type field to LeadsLocState.auth_exhibit_kv interface (was set at runtime but missing from type)
- Silence QR code console noise: entry log gated at log_lvl >= 2, data URL log removed
- vite.config.ts: exclude documentation/ and tests/ from Vite HMR file watcher
