test(e2e): update replay payload specs to schema v4

PR #170 changed the web replay payload (moves list -> embedded session
recording) but missed these Playwright specs, which only run on master
pushes and so failed post-merge. Assertions now match the v4 shape:
schema_version 4, recording.initial_state present, moves at
recording.instructions.

Verified locally against a real server with freshly built wasm bundles:
full suite 18/18 green, including the five play_canvas specs.

+### Fixed
+
+- **Replays are now self-contained (schema v4).** A replay stores the dealt
+  board itself via the upstream `card_game` session serializers instead of
+  re-dealing from the seed at playback time, so replays survive RNG and
+  upstream upgrades that change the seed→deal mapping — the failure that had
+  silently broken every stored replay. The web player and web game now
+  exchange the full payload through the wasm layer (the old JS path hardcoded
+  `schema_version: 2`, uploaded empty move lists, and corrupted u64 seeds via
+  `Math.round`), and the replay viewer reports unplayable old-format replays
+  in the caption instead of dying silently. Pre-v4 replays are rejected by a
+  version gate; local histories repopulate with new wins. (#170)
+- **Difficulty-mode wins can upload.** The server's replay `mode` validation
+  now accepts data-carrying `GameMode` variants (previously a 400). (#170)
+
