My Sea iter 4b: MySeaDraw persistence + LOCK HAND POST + DEL guard + Brief banner; rewrite obsolete spread-switch FT; fix bud-panel CI race on gatekeeper FT — Sprint 5 iter 4b of My Sea roadmap — TDD

Iter 4b lands server persistence of the iter-4a client-side hand. New MySeaDraw model (FK user, spread, hand JSONField in draw order, sig snapshot, created_at) w. 1/24h quota window; new endpoints /gameboard/my-sea/lock (POST, 409 on quota-active, 400 on partial hand) + /gameboard/my-sea/delete (POST, idempotent). LOCK HAND now collects the in-progress hand from DOM, POSTs, and on success un-hides a Brief banner inline (no page reload — preserves iter-4a FT picker refs). DEL post-LOCK opens #id_my_sea_del_portal w. uniform 'Are you sure?' copy; CONFIRM POSTs delete + reloads to landing. Brief banner carries the next-free-draw timestamp + a NVM dismiss. Saved-draw render bypasses the sign-gate via _resolve_sig (sig snapshot on the draw is used even if user.significator was cleared later) + bypasses the landing phase (the saved hand IS what the user came to see). Per-position slot rendering extracted to _my_sea_slot.html. DRY follow-up: card_dict() extracted to apps.epic.utils — gameroom sea_deck + my-sea _my_sea_deck_data now share one source of truth (prevents drift like the iter-4a-follow-up Major Arcana fix from recurring).

Pipeline #316 fixes bundled: (a) functional_tests.test_game_my_sea.MySeaCardDrawTest.test_switching_spread_resets_in_progress_hand was obsoleted by the iter-4a follow-up's spread-lock-after-first-draw — the test premise (mid-draw spread switching resets hand) no longer matches behavior (switching is blocked outright). Rewrote as test_first_draw_locks_spread_combobox, which pins .sea-select--locked after first draw + verifies DEL releases it. (b) functional_tests.test_game_room_gatekeeper.GatekeeperTest.test_second_gamer_drops_token_into_open_slot failed in CI on ElementNotInteractableException when clicking #id_bud_panel .btn.btn-confirm — the bud panel's scaleX(0)→scaleX(1) 0.2s CSS transition wasn't settled by click-time, so Selenium read scroll-into-view against a near-zero-width target. Added a wait_for on getBoundingClientRect().width > 100 so the click waits for the animation to finish. Local passes consistently; CI was 1+ frame slower than the implicit 'find element' wait.

Tests: 1085 IT/UT green in 55s; 35 my_sea FTs green in 5m; new ITs in MySeaDrawModelTest (8), MySeaLockHandViewTest (7), MySeaDeleteDrawViewTest (5), MySeaViewWithSavedDrawTest (9); new FTs in MySeaLockHandTest (5).
