my_sea AUTO DRAW: flash FLIP btn per-card for monodecks too — fall back to --single stack

User-spec 2026-05-26 PM: "AUTO DRAW on my_sea.html, when featuring gravity and levity decks, displays the FLIP .btn-reveal atop each card just before the next dealt card appears in the next card slot. Can you update the monodeck AUTO DRAW animation sequence to feature this FLIP .btn-reveal every time the AUTO DRAW runs here too?"

`placeNext` (inside `_autoDraw` in the my_sea.html inline IIFE) was querying `.sea-deck-stack--levity` / `.sea-deck-stack--gravity` only — polarized decks (Earthman) render those stacks + flash their FLIP btn between dealt cards via `_showOk(stack)`. Monodecks (Minchiate, RWS) render only `.sea-deck-stack--single`, so the polarity-keyed query returned null and the per-card FLIP-flash never fired.

One-line fix: `|| picker.querySelector(".sea-deck-stack--single")` fallback after the polarity-keyed query. `_showOk` + `_hideOk` already operate uniformly on whatever stack is passed in (the `.sea-stack-ok` btn renders identically in both template branches), so no other changes needed.
