fix CI FT regression: My Sign + My Sea setUpClass ContentType collision — pipeline #313

Sprint 4a-cont (400762c) + 4b (cd0add1) introduced `serialized_rollback = True` on `MySignPickerTest`, `MySignBackupDeckTest`, and `MySeaSignGateTest` to keep migration-seeded `DeckVariant` + `TarotCard` rows alive across TransactionTestCase flushes. Locally each file ran clean, but in the full pipeline #313 `test-FTs-non-room` stage all three classes errored in setUpClass:

  django.db.utils.IntegrityError: UNIQUE constraint failed:
  django_content_type.app_label, django_content_type.model

Mechanism: every prior `TransactionTestCase`-derived class in the bucket flushed without `inhibit_post_migrate`, so Django's post-migrate signal recreated `django_content_type` rows. When these three classes hit `_fixture_setup` & tried to deserialize the saved DB snapshot, the inserts collided on `(app_label, model)`. No serialized rollback ⇒ no collision; mixing in the same DB run is the trap.

Fix: drop `serialized_rollback = True` from all 3 classes & inline-reseed via `get_or_create` per the canonical pattern already used by [test_admin_tarot.py](src/functional_tests/test_admin_tarot.py) & [room_page.py](src/functional_tests/room_page.py) (see [[feedback_transactiontestcase_flush]]) — new `_seed_earthman_sig_pile()` module-level helper in each file restores `DeckVariant(slug='earthman')` + the 16 MIDDLE court cards (Maid/Jack/Queen/King × BRANDS/CROWNS/BLADES/GRAILS) that `personal_sig_cards(user)` returns.

Adjacent bug uncovered once the snapshot reload was gone: [test_game_my_sea.py](src/functional_tests/test_game_my_sea.py) `_seed_gameboard_applets` had been seeding `my-palette` w. `context='gameboard'` — but `my-palette` is not a gameboard applet (it's a dashboard slug; the real palette applet is `palette` per migration 0003). The applets template iterates every applet & includes `apps/<context>/_partials/_applet-<slug>.html`, so seeding the bogus row made /gameboard/ try to load a partial that doesn't exist → TemplateDoesNotExist 500 → `#id_applet_my_sea` never rendered. `serialized_rollback = True` had been masking this because the snapshot restored the migration-correct applet rows (which never had my-palette as a gameboard entry to begin with). Swapped `my-palette` for the real `new-game` gameboard applet & corrected grid-cols/rows on `game-kit` to match the 0003 seed (4×3, not 4×6).

Tests: full sweep across all three classes runs green locally (17/17 in 142s).
