Sea Select: spread center significator supplies the card-face image — TDD

The felt cross's CENTER significator was hardcoded to the corner-rank + suit-icon
text thumbnail, so an image deck (RWS / Minchiate) showed a bare "0"+icon card
instead of its face. Mirror my_sea: render the `.sig-stage-card-img` (image mode)
when the sig's deck has card images, else fall through to the text thumbnail. The
tray sig stays the simple thumbnail (user-spec). The sig's `deck_variant` is the
card's OWN deck — the Sig Select pick is drawn from the Role Select contributed
deck (`_room_deck_variant`), so this is the correct image source (no equipped_deck
bug, unlike the earlier FLIP back-img).

- IT: an image-deck significator renders the center `sea-sig-card sig-stage-card--image`
- 949+ epic ITs green

; FLIP tint tweak (parallel edit): flipped-back overlay alpha 0.6 → 0.3
