fix(container): use scoped binding for parser

KmlParser holds the loaded SimpleXMLElement as instance state, so the
singleton binding kept a parsed document alive across Octane requests
and across jobs in a long running queue worker. Any consumer resolving
the parser without loading first could read another request's document.

A scoped binding keeps the instance stable for the whole request or job
(so the documented facade chaining still works) while the container
flushes it between lifecycles.
