feat(reports): reports module + /inicio + edo-cuenta-datos prefill

- New reports backend (registry, service, controller, outputs, types)
  with catalog endpoint + slug/CSV/XLSX/PDF/print outputs.
- /reportes catalog + /reportes/[slug] runner; ReportRunner + ContextReports
  components wire pre-filtered links from domain pages.
- Fix: /reportes/[slug] now reads searchParams and forwards initialParams to
  ReportRunner so /reportes/edo-cuenta-datos?customerId=... auto-runs
  instead of dropping the id and forcing a manual customer search.
- /inicio landing page; root + login redirect to /inicio.
- Company header env vars + logo asset for PDF/print rendering.
- exceljs + pdfkit deps.
