funman300 07b8ecd9b2 feat(server): web replay viewer (HTML/CSS + WASM bindings)
Wires the WASM module from the previous commit into a minimal web
viewer served at <server>/replays/<id>. Two new server routes:

- `GET /replays/:id`  — returns the same embedded HTML page for any
  id; the page itself reads the path from window.location in JS and
  fetches the replay JSON via /api/replays/:id.
- `/web/*` — ServeDir for the static assets (replay.css, replay.js,
  and the wasm-bindgen-generated pkg/).

Web layer:
- index.html — header, board, controls, status. Module script.
- replay.css — midnight-purple palette matching the desktop client,
  dark felt board, CSS-grid pile layout, tableau fan via per-card
  inline `top` offset.
- replay.js — fetches the replay, instantiates the wasm
  ReplayPlayer, drives state(), step(). Controls: Restart, Play/Pause
  toggle, Step. Auto-tick at 600 ms.
- pkg/ — generated by wasm-bindgen (committed so deployers don't
  have to install wasm-bindgen-cli + the wasm32 target).

`tower-http = "0.6"` added to solitaire_server with the `fs` feature
for ServeDir.

To regenerate pkg/ after a solitaire_wasm change:
    RUSTFLAGS='--cfg getrandom_backend="wasm_js"' \
      cargo build -p solitaire_wasm \
      --target wasm32-unknown-unknown --release
    wasm-bindgen --target web \
      --out-dir solitaire_server/web/pkg --no-typescript \
      target/wasm32-unknown-unknown/release/solitaire_wasm.wasm
