fix(import): strip CDK project prefix from OEC service name when resolving agent

CDK constructs set the OEC service name as "{projectName}_{agentName}.DEFAULT".
extractAgentName() strips ".DEFAULT" but not the project prefix, so the
lookup fails against local runtime names. Now strips the prefix as a fast
path before falling back to the deployed-state API lookup.
