source-shopify-native: support multiple Shopify stores

Add support for capturing data from multiple Shopify stores in a single capture task. Key changes:

- Endpoint config now accepts a list of stores with individual credentials
- State is always dict-based, keyed by store_id
- Collection keys include `/_meta/store` for new captures
- Legacy single-store captures maintain backward compatibility with `["/id"]` keys
- Automatic state migration from flat to dict-based format
- Validation ensures backfill acknowledgment when:
  - Adding multiple stores to a legacy capture
  - Re-enabling bindings that missed a key structure transition
