feat(packs): PackDrawTableImporter with fixture tests

Browse Source 
Idempotent upsert keyed on pack_id; slot rates and card weights are
wiped per pack and reinserted. String slot/tier in the seed translate
to enum at import time.

Tests:
- Imports_config_slot_rates_and_card_weights
- Is_idempotent_on_rerun

Fixtures live under SVSim.Bootstrap/Data/test-fixtures/seeds/ and overlay
the production seeds via the existing csproj rule (test-fixture file
beats production file at same Link path).
