Log Explorer: monitor security events without third-party storage

Introduced Log Explorer, a new feature that allows users to investigate HTTP and Security Event logs directly within the Cloudflare Dashboard. Log Explorer is built on Cloudflare R2 and leverages the Delta Lake protocol for ACID-compliant storage and querying. It provides a SQL interface for analyzing raw log data, enabling detailed security investigations and reducing the need for third-party log storage solutions. This enhances the capabilities of Security Analytics by providing granular log access.
