build(deps): switch card_game/klondike to mainline fb01881f

Move both crates off the damaged "hacked" rev 99b49e62 onto mainline
master (card_game 0.4.0->0.4.1, klondike 0.3.0->0.4.0) to pick up the new
serialize implementation.

Mainline drops the serde derives from Deck/Suit/Rank (only Card is serde
now, as a compact transparent NonZeroU8) and gives KlondikeInstruction a
hand-written serde impl. Adapt the repo:
- Rank::value() was removed; the enum discriminant is the 1..=13 value, so
  use `rank as u32/u8` in the three card_to_id helpers (wasm, radial_menu,
  feedback_anim).
- Drop the vestigial Serialize/Deserialize derive on theme::CardKey; theme
  manifests address faces by manifest_name strings, never by serialising
  CardKey, and Suit/Rank no longer implement serde.

GameState's own instruction-mirror serde (schema v3/v4) is insulated from
the klondike serde change, so the on-disk save format is unchanged.

cargo test --workspace and cargo clippy --workspace -- -D warnings pass.
