fix(reports): split PDF widget catalogue out of the DB-touching service

export-dashboard-pdf-button.tsx imported PDF_DASHBOARD_WIDGETS +
PdfDashboardWidgetId from dashboard-report-data.service.ts. JS modules
evaluate their imports eagerly, so the button transitively pulled in
that file's top-level `import { getKpis } from './dashboard.service'`,
which pulled in `@/lib/db`, which pulls in `postgres`, which crashed
the client bundle with:

  Module not found: Can't resolve 'fs'
    ./node_modules/.../postgres/src/index.js [Client Component Browser]

Split the pure data + types into the new file
src/lib/services/dashboard-report-widgets.ts and re-export from the
original service for backwards compatibility. The button now imports
from the pure file; the server-only route (reports/generate) keeps
using the resolver as before.

tsc clean, dashboard loads.
