yoda: absorb upstream theme-v2 integration debt post-rebase

- degate 'feature = "winit"' cfgs added by upstream (fork policy:
  winit toujours actif, le stub Cargo reste vide)
- cards.rs: restore 'id' param consumed by upstream's new struct init
- iced submodule rebased onto upstream c781ff61 (wgpu 28, cryoglyph)
- Cargo.lock regenerated against local path deps
