tarot card icons + ranks; sig fallback for pre-sync Characters; DECKS label sizing — TDD

- migration 0011: The Nomad (0) → fa-hat-cowboy; The Schizo (1) → fa-hat-wizard
- corner_rank: non-MAJOR pip card 1 → 'A' (Ace); court unchanged (M/J/Q/K); TDD
- 17 unit model tests for corner_rank + suit_icon
- _role_select_context: my_tray_sig falls back to seat.significator when
  confirmed_char.significator is None (Characters created before natus_save sync)
- _card-deck.scss: DECKS label bigger (1rem, 0.32em letter-spacing) to fill
  stack height; sea-stack-name: opacity 0.6, scaleY(1.5), margin-top -0.4rem
  partially under face; sea-stack-face z-index:1
