Subject: [PATCH] Fix MySQL compatibility: EscapeName backticks, REPLICATION
 REPLICA

- Escape embedded backticks in EscapeName by doubling them, preventing
  broken SQL identifiers (builder.go)
- Accept REPLICATION REPLICA privilege in grant check for MySQL 8.4+
  compatibility, where REPLICATION SLAVE was renamed (inspect.go)
