feat(series): add series/cup championships with points tables and standings

Group any number of races in freely chosen classes into a series with a
points table (ÖRC/100-80-70/F1/custom), best-N or drop-X counting, a
club filter that re-ranks members without guests, tie-breaks, rounds
created from a date list, and per-class standings with print and PDF.

Also fixes PDF export of wide tables: they are compacted and switched
to landscape instead of truncating names and dropping columns.
