Audit log export

You can now send your organization's Ryvn API audit logs to a storage bucket you own, so who changed what in Ryvn sits alongside the rest of your security records. Ryvn generates a setup script that grants it write access under the prefix you choose and starts exporting only after it confirms that access, then delivers compressed JSON Lines files to your bucket. See audit export for coverage, S3 and GCS setup, and limits.
