fix(cart-recovery): filter candidate line counts by active and non-deleted products

[Pratyush-Panda-2006]

Description

Fixes erroneous abandoned cart recovery email dispatches for baskets containing only soft-deleted or withdrawn products in \�ackend/services/cartRecoveryService.js. Previously, \indRecoveryCandidates\ performed a raw subquery count on \cart_items, sending recovery emails for abandoned carts whose items were unpurchasable and resulting in HTTP 410 dead-ends upon clicking the restore link.

Related Issue

Closes #1725

Clean Architecture & Changes

• Updated the \line_count\ subquery in \indRecoveryCandidates()\ to join \products p\ and enforce canonical \publicProductCondition('p').
• Added unit tests in \�ackend/tests/cartRecoveryCandidateFilter.test.js\ validating line count query construction and active/non-deleted product filtering.

Verification

• Run
  px jest tests/cartRecoveryCandidateFilter.test.js\ (All unit tests passing cleanly).
