/**
 * Handler for deleting records of a model.
 *
 * To use this handler, you must import it first and call it with the necessary parameters. For example:
 * ```javascript
 * const { importModule } = this.app.bajo
 * const deleteHandler = await importModule('waibuDb:/lib/crud/delete-handler.js')
 * await deleteHandler.call(this, { model: 'YourModelName', req, reply })
 * ```
 * @async
 * @memberof module:CRUDHandler
 * @method
 * @param {object} opts - Options object
 * @param {object} opts.req - Request object
 * @param {object} opts.reply - Reply object
 * @param {string} opts.model - Model name
 * @param {object} [opts.params={}] - Parameters for the template
 * @param {string} [opts.templateDisabled='waibuDb.template:/disabled.html'] - Disabled template path
 * @param {object} [opts.options={}] - Additional options
 * @returns {Promise<void>} Redirects to the list view
