Pull request overview

This PR adds update/enable/disable capabilities for scheduler “batch actions” by moving batch-action ownership metadata onto scheduled_task (removing the separate batch_action table) and exposing a new PUT endpoint for updating an existing batch action.

Changes:

• Add owner to scheduled_task, migrate existing batch_action.owner data, and drop the batch_action table.
• Update scheduler SQLC queries/repo methods to read/write/list scheduled tasks by owner for the batch-actions API.
• Extend the scheduler API/OpenAPI and tests with PUT /batch_actions/{id} plus enable/disable endpoints.
