feat(data-access): add allByEnrollmentProductCode to SiteCollection

[jindaliiita]

Summary

• Adds allSiteIdsByProductCode(productCode) to SiteEnrollmentCollection — performs a single PostgREST JOIN query (site_enrollments ⨝ entitlements) to return all site IDs enrolled in a given product code
• Adds allByEnrollmentProductCode(productCode, options) to SiteCollection — uses the above to scope site fetching to a specific product (e.g. LLMO), then batch-fetches full Site objects with caller-controlled field projection via options.attributes
• Adds unit tests with 100% coverage for both new methods (9 new test cases across 2 files)

Motivation

Required by the optimize-at-edge-enabled-marking import worker job, which previously fetched all sites via Site.all(). Scoping to LLMO-enrolled sites reduces unnecessary data transfer and in-memory filtering as the DB scales.

Test plan

• SiteEnrollmentCollection — allSiteIdsByProductCode: falsy input, happy path with data, empty data, null data, DB error
• SiteCollection — allByEnrollmentProductCode: falsy input, empty site IDs (early return), default options, custom options forwarded to batchGetByKeys
• All 40 tests in both collection test files pass

I am able to see it for site ID 1f09e6f5-ad35-4772-bdbb-c1b19a364c4f and org ID d6bfa68d-c137-4203-acd5-1ac7d2d49d84, but not sure if I am missing something.
