Add solde footers + per-année small multiples to /dashboard/compte

1. "Entrées sur-versées" and "Versements sans entrée liée" tables get a
   solde footer, same convention as "Reste à verser" above them --
   reuses the totalSurVerse/totalNonLies computeds already backing the
   summary cards, no new computation.

2. "Répartition de l'activité par type" and "Top clients" keep their
   all-time chart, now followed by a small-multiples grid of the same
   chart per année. The type breakdown reuses
   total_par_type_par_compte_par_annee, a new field on
   DashboardStatsController::stats() built from the same répartition-
   level rows already fetched for total_par_type_par_compte (no extra
   query, just one more level of grouping in the PHP aggregation). Top
   clients per année is computed client-side from the same
   entreesDuCompte already used for the all-time version, capped to top
   5 (not 10) to keep the grid readable.

HBarChart gains a `compact` prop (narrower fixed columns, smaller text)
for use inside the small-multiples cards -- the all-time charts above
keep the full-width layout unchanged.
