Context

Threshold-based wallet top-ups can sometimes enqueue duplicate jobs if the job is triggered multiple times within a short time window. This leads to unnecessary or duplicate credit grants.

To prevent this, we want to ensure that these jobs are uniquely enqueued based on relevant identifiers: organization_id, wallet_id, paid_credits, and granted_credits.

Description

This PR adds job uniqueness handling to WalletTransactions::CreateJob using sidekiq-unique-jobs, but only when the unique_transaction flag is set to true.

• Introduced conditional uniqueness based on unique_transaction
• Fallback to non-unique behaviour when the flag is not set

This keeps behaviour backward-compatible for other use cases of CreateJob, while enforcing uniqueness where it matters.
