fix(bundle): remap installed workflow step metadata

[chubes4]

Summary

• Fixes agent bundle installs so pipeline and flow step IDs are remapped to the installed pipeline/flow IDs.
• Prevents imported flows from carrying stale bundle-local pipeline_id / pipeline_step_id metadata into runtime execution.

Changes

• Remap pipeline config keys and embedded pipeline_step_id values after install/update.
• Remap flow config keys plus embedded flow_step_id, pipeline_step_id, pipeline_id, and flow_id values once the installed flow ID is known.
• Extend the portable bundle smoke test to cover runtime metadata remapping.
