add per-game accuracy and outcome table to stats/notifications

Games-of-period responses can now include a per-game breakdown
(include_games) with Lichess post-analysis accuracy, plus which side
the tracked player was on and their rating change for that game.

- lichess_client.py requests accuracy=true from Lichess; stats_service
  computes per-mode average accuracy and builds GameRow entries
  (tracked_is_white, tracked_rating_diff) for blitz/rapid/classical
- /games/{username}/period gained an include_games query param
- formatters.py renders a column-aligned monospace table per game:
  outcome circle (win/loss/draw relative to the tracked player),
  rating change, accuracy, names/ratings, result — for today/yesterday
  and periodic notifications; week keeps an aggregate accuracy line
- usernames are Markdown-escaped before formatting since messages are
  now sent with parse_mode='Markdown'
