"""Add missing tables: mtg_sets, mtg_cards, mtg_cards_mirror, card_import_batches, user_card_imports_confirmed, deck_card_links

Revision ID: 005
Revises: 004
Create Date: 2026-01-05 00:00:00.000000

This migration creates the following tables using raw column definitions
to avoid circular import issues with the ORM models.

  - mtg_sets, mtg_cards          → raw definitions (mirrors mtg_models.py)
  - mtg_cards_mirror, deck_card_links  → raw definitions (mirrors mirror_models.py)
  - card_import_batches          → raw definitions (mirrors card_import_batch.py)
  - user_card_imports_confirmed  → raw definitions (mirrors user_card_import_record.py)
