Test first: sandbox-admin-list.feature verifies createdAt, expiresAt,
unauth rejection, and admin delete — three new BDD scenarios.
Bug found: listAllSandboxes() native query mapping used
instanceof java.sql.Timestamp, but Hibernate 6 + PostgreSQL JDBC
returns LocalDateTime for timestamptz columns. toInstant() now
handles Timestamp, OffsetDateTime, ZonedDateTime, LocalDateTime (UTC),
Date, and any Temporal via Instant.from() fallback.
UI change (admin list "Created" column, prior commit) now has
test coverage at the API layer.
