IMPROVEMENTS:

• Update github.com/dvsekhvalnov/jose2go to fix security vulnerability CVE-2025-63811.
• api: Added sudo-permissioned sys/reporting/scan endpoint which will output a set of files containing information about Vault state to the location specified by the reporting_scan_directory config item.

• core/metrics: Reading and listing from a snapshot are now tracked via the vault.route.read-snapshot.{mount_point} and vault.route.list-snapshot.{mount_point} metrics.
• license utilization reporting (enterprise): Add metrics for the number of issued PKI certificates.
• policies: add warning about list comparison when using allowed_parameters or denied_parameters
• secret-sync: add parallelization support to sync and unsync operations for secret-key granularity associations
• secrets/pki: Include the certificate's AuthorityKeyID in response fields for API endpoints that issue, sign, or fetch certs.
• sys (enterprise): Add sys/billing/certificates API endpoint to retrieve the number of issued PKI certificates.
• ui/activity (enterprise): Add clarifying text to explain the "Initial Usage" column will only have timestamps for clients initially used after upgrading to version 1.21

• auth/aws (enterprise): Role parameter alias_metadata now populates alias custom metadata field instead of alias metadata.
• auth/cert (enterprise): Role parameter alias_metadata now populates alias custom metadata field instead of alias metadata.
• auth/github (enterprise): Role parameter alias_metadata now populates alias custom metadata field instead of alias metadata.

• ui (enterprise): Fix KV v2 not displaying secrets in namespaces.
• ui (enterprise): Fixes login form so input renders correctly when token is a preferred login method for a namespace.
• ui/pki: Fixes certificate parsing of the key_usage extension so details accurately reflect certificate values.
