feat(assets): swap card art to hayeah/playing-cards-assets (MIT)

Replaces the previous xCards-derived card faces (LGPL-3.0) with
hayeah/playing-cards-assets, which itself derives from the
public-domain vector-playing-cards Google Code project. The whole
package is MIT now — see CREDITS.md for the new attribution table
and the simpler license summary.

solitaire_engine/assets/themes/default/
  52 face SVGs (clubs/diamonds/hearts/spades × ace/2-10/jack/queen/
  king) — copied from hayeah, renamed to the canonical
  `{suit}_{rank}.svg` form `CardKey::manifest_name` produces. The
  bundled default theme manifest references each by the same name.
  back.svg — original midnight-purple-themed card back, hand-written
  to match the project's design tokens (BG_BASE / BG_ELEVATED /
  ACCENT_PRIMARY / ACCENT_SECONDARY). MIT, original work.

assets/cards/faces/{RANK}{SUIT}.png
  52 PNGs regenerated from the new SVGs at 750-tall via resvg 0.47.
  These remain the legacy backwards-compat path that
  `card_plugin::load_card_images` reads at startup; once the runtime
  theme system finishes loading the embedded default theme, the
  CardImageSet's face handles are overwritten with the SVG-rendered
  variants and these PNGs become moot. Keeping them in place avoids
  a brief blank-card flash before the async theme load completes.

solitaire_engine/src/assets/sources.rs
  embed_default_svg!() macro + DEFAULT_THEME_SVGS table that bundles
  every face + the back into the binary at compile time via
  include_bytes!. populate_embedded_default_theme now iterates the
  table so the EmbeddedAssetRegistry is populated under the same
  asset paths the manifest references.

CREDITS.md
  License summary collapses from MIT + LGPL-3.0 + OFL-1.1 to MIT +
  OFL-1.1 (the OFL still applies to FiraMono). The hayeah upstream
  URL replaces the previously-blank xCards entry.

xCards is the playing-card artwork bundle by Huub de Beer, published under the
LGPL-3.0. The art is consumed as unmodified PNG files at runtime; the game
binary statically links no LGPL code, so distribution as a self-contained
binary plus the `assets/` directory satisfies the LGPL's relinking clause.
The face SVGs come from Howard Yeh's `playing-cards-assets` repository, which
is itself derived from the public-domain `vector-playing-cards` Google Code
project. The art is redistributed under the MIT license — see the upstream
repository for the full notice. The files ship unmodified in the bundled
default theme; user-supplied themes can override them per-installation
through the runtime SVG theming system documented in `CARD_PLAN.md`.
The default card back is original work by this project, midnight-purple
themed to match the rest of the UI palette.
