refactor: split round spread and rating range into separate accordion rows (#19)

- Add "Round spread" row (±stdDev, range lo–hi) to desktop accordion
  (player-history.ejs) and mobile card expanded section (ratings-cards.ejs)
- Remove .std-dev-tooltip div and .std-dev-inline span from table partial
- Remove stdDevTooltipText, updateStdDevInline, initRatingsTooltips helpers
  and all call sites from players.js
- Remove .std-dev-tooltip and .std-dev-inline CSS rules; drop cursor:help
  from .rating-value
