## Problem

`app/routers_v2/cards.py` — `v1_cards_get_one` endpoint's CSV branch accessed `this_card.roster1.name`, `this_card.roster2.name`, `this_card.roster3.name`. The `Card` model has no such fields, so any `GET /api/v2/cards/{id}?csv=true` request would raise `AttributeError` at runtime.

## Root Cause

The CSV code was written against an older schema that had roster foreign keys on `Card`. Those fields were removed from the model but the CSV export code was never updated.

## Solution

Removed the three dead columns from the CSV header row and data row. The output now reflects only fields that exist on `Card`: `id`, `player`, `team`, `pack`, `value`.

## Files Changed

- `app/routers_v2/cards.py` lines 144–146

## Note

The `v1_cards_patch` endpoint also accepts `roster1_id`, `roster2_id`, `roster3_id` params that are silently ignored (no assignment in handler body) — dead API surface but not a runtime error.
