fix: make sure we use partial index when creating scheduled and cron refs

[mnafees]

Description

When creating scheduled and cron refs we were not properly filtering for latest workflow version and hence not using the desired partial index idx_workflow_version_workflow_id_order which can lead to high CPU when there are millions of rows in the respective tables.

Type of change

• Bug fix (non-breaking change which fixes an issue)

What's Changed

• Add a clause deletedAt IS NULL to existing SQL CTEs when filtering for latest workflow versions.

Checklist

Changes have been:

• Tested (unit, integration, or manually with steps specified)
• Linted and formatted

Pull request overview

This PR fixes workflow version lookup used when creating cron and scheduled trigger refs so queries filter to non-deleted workflow versions, allowing Postgres to use the intended partial index (idx_workflow_version_workflow_id_order) and avoid high CPU on large tables.

Changes:

• Add AND "deletedAt" IS NULL to the latest_version CTE used for cron trigger ref creation.
• Add AND "deletedAt" IS NULL to the latest_version CTE used for scheduled trigger ref creation.
• Regenerate/update the corresponding sqlc-generated .sql.go query constants.
