P0: Deck domain types (types.ts)

[Doberjohn]

Define the deck domain types in apps/web/src/features/deck/types.ts, the shared vocabulary for the whole feature.

Scope

• Deck (incl. optional gameplan), DeckCard { cardId, quantity, isCore? }, DeckStats, DeckHealth, HealthAnalyzer, Vulnerability, Suggestion, Archetype (incl. 'ramp'), QualityScore, AnalysisCase, DeckFingerprint.
• Store cardId (string), never the whole LorcanaCard — hydrate via getCardById.
• Any type guards get focused tests.

Notes: LorcanaCard/Ink/CardType come from inkweave-synergy-engine (import type).

Part of #450 · Deck Builder & Engine Score milestone.

Delivered and merged into the deck-builder integration branch via #480 (not yet in production / master). Closing as complete; it rides to production when deck-builder later merges to master.
