Games: in-progress hub status + distribution-aware word-search placement (Codex)

- Play hub: word cards now surface IN-PROGRESS games too (not just won/lost) so
  "continue on another device" shows at a glance — card reads "5:3…" and the
  selection option says "Continue · 3/6".
- Word Search generator: replace "prefer any crossing" with a SCORED placement —
  score = overlap*4 - local crowding (filled neighbours that aren't crossings) —
  then pick among the best ~20%. Keeps the organic interlocking but spreads words
  across the board instead of clumping around the first-placed (longest) words.
  Every word still placed (tests green). NOTE: changes today's grid layouts, so
  an in-progress word search resets once.

237 pytest + 11 vitest green.
