src/lib/dates.ts is the single source for month names and date
formatting; the three per-page month arrays are gone (with an
off-by-one guard — the shared array is 1-indexed). formatDate and the
Analytics chart tooltips now speak es-CR, Analytics headings are
Spanish, and the cycle selector says 'Todo el período' (UX-19, FE-17,
UX-07).
