fix: manual my-sea draws persist on refresh + reloaded slots stay clickable — root cause was SeaDeal stamping slot.dataset.posKey w. selector form (".sea-pos-cover") while my-sea's inline _collectHandFromDom + template's _my_sea_slot.html use raw names ("cover"). Key mismatch silently dropped manual draws from the lock POST → server rejected empty hand → no row → refresh showed empty state. AUTO DRAW worked only because it assembled fullHand w. raw posNames directly, bypassing the broken collector. TDD — 2 new FTs pin the contract:

- test_manual_draw_persists_on_refresh
- test_reloaded_slot_can_reopen_stage_modal_on_click

Changes:
- sea.js: stamp `dataset.posKey` w. raw name (strip `.sea-pos-` prefix); `_seaHand` keyed by raw; `_viewingPos` is raw too (`_hideStage` prefixes when querySelector'ing); new `SeaDeal.seedHand(handByPosName)` public method for init-time DOM-walk seeding.
- my_sea.html inline init: walk server-rendered filled slots, look up each card by `data-card-id` from the embedded deck JSON, reconstruct per-instance `reversed` + polarity from the slot's classes, hand the map to `SeaDeal.seedHand`. Without this, reloaded slots short-circuit the overlay click handler on `if (!_seaHand[pos]) return;`.

The gameroom-side SeaDeal callers in `_sea_overlay.html` continue to pass selector form (SeaDeal accepts either — `_posName` helper strips prefix tolerantly).
