Execute an admin operation with timeout.

Admin operations include DDL (CREATE TABLE, ALTER, etc.), DML (INSERT, UPDATE, DELETE), and read queries. This is the most privileged execution level.

Arguments

• system - The actor system to execute the admin operation on
• engine - The database engine to execute the admin operation on
• statements - The RQL admin statements
• identity - The identity context for permission checking
• params - Admin parameters
• timeout - Maximum time to wait for admin completion

Returns

• Ok(Vec<Frame>) - Admin results on success
• Err(ExecuteError::Timeout) - If the admin operation exceeds the timeout
• Err(ExecuteError::Cancelled) - If the admin operation was cancelled
• Err(ExecuteError::Engine) - If the engine returns an error
