Add getMonthlyHistory() to models/player for single-player use and
getAllMonthlyHistoriesFromDB() for bulk fetches (one query, grouped in
memory). Wire monthlyHistory into all player objects returned by
getPlayerDataFromDB and getAllRatingsFromDB. Bulk path pre-fetches in
one query to avoid N extra per-player queries.
Introduce new design token set (paper/ink/line/accent + radius/shadow)
with backward-compat aliases for legacy --surface/--navy/--text names.
Swap DM Sans for Plus Jakarta Sans, add JetBrains Mono with tabular
numerics. Replace .app-header with sticky .topbar partial (brand +
segmented nav + Next update / Last refresh meta + Refresh all button).
Add POST /api/refresh-all that runs refreshAllPlayersInDB() with an
in-memory mutex and returns the rendered topbar so HTMX can swap it
in. "Next update" is computed as first Tuesday of next month
(approximation of PDGA's monthly cycle). "Last refresh" derives
from MAX(players.last_updated).
