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).
