My Sea picker phase: three-card cross (sig + cover/leave/loom) — Sprint 5 iter 2 of My Sea roadmap — TDD

After the FREE DRAW click on iter 1's landing swaps `data-phase` to `picker`, the picker now renders a stripped Celtic Cross: user's saved significator pinned in `.sea-pos-core`, three drawn-card drop zones around it — cover (overlaid on sig), leave (left of core), loom (right of core). Crown / lay / cross from the gameroom's 6-position spread are deliberately forsaken (user-locked spec).

DRY w. the gameroom sea-overlay: reuses `.sea-cards-col` + `.sea-cross` + `.sea-crucifix-cell` + `.sea-pos-*` + `.sea-card-slot--empty` + `.sea-sig-card` classes & their _card-deck.scss styling (1181-1331). Only divergence from the room: a `.my-sea-cross` modifier in `_gameboard.scss` overrides `grid-template-areas` from the room's `". crown . / leave core loom / . lay ."` 3×3 to a single-row `"leave core loom"` — drops the crown + lay rows since those positions are forsaken. Cover stays nested inside `.sea-pos-core` so the absolute-overlay rules from _card-deck.scss line 1310-1331 carry over for free.

Picker bg = `rgba(var(--duoUser), 1)` on `.my-sea-page[data-phase="picker"]` — parallels `.my-sign-page[data-phase="picker"]` from _card-deck.scss line 704, so the landing→picker swap reads as a continuous surface (hex face → felt) like on /billboard/my-sign/.

The sig card renders w. `data-card-id="{{ significator.id }}"` + `.fan-corner-rank` + `.fa-solid {suit-icon}` (mirrors the gameroom's `.sea-sig-card` minimal markup at `_sea_overlay.html` line 33-39). Full card-face / FYI / SPIN wiring deferred — iter 3 lands the form col + interactive draw flow.

View context: `my_sea` now passes `significator` (FK pass-through) + `significator_reversed` so the template can render the corner rank + suit icon at render time without re-fetching.

- 3 FTs in new `MySeaPickerPhaseTest`: sig card w. `data-card-id` matching `user.significator.id` in `.sea-pos-core`; cover/leave/loom empty drop zones render; crown/lay/cross absent. Shared `_enter_picker_phase()` helper polls for `data-phase='picker'` after the ~800ms seat-1C animation delay.
- 4 ITs in new `MySeaPickerPhaseTemplateTest`: server-render contract for sig in core + cover/leave/loom classes + forsaken-positions-absent + picker entirely absent when user has no sig (4b gate precedence).

Tests: 28/28 FT green across test_bill_my_sign + test_game_my_sea (~219s); 1041/1041 IT/UT green (53s).
