refactor: decouple card effects from card data in desert sample

Moves card effects from `card.csv` to a dedicated `cardEffect.csv` file.
This allows for more granular control over card triggers (onPlay,
onDraw, onDiscard) and targets, improving the data model for the
slay-the-spire-like sample. Also updates triggers and tests to
reflect this new structure.
