fix: don't delete or fail to update conditions when their parent step…

[Ruari-Phipps]

Summary

Fixes two bugs in _clean_resources_before_push that caused push failures when a flow step with conditions was deleted.

Motivation

When a FlowStep is deleted, Agent Studio automatically deletes its child Conditions server-side. This caused two issues:

1. Explicitly including the condition in deleted_resources would result in a double-delete error.
2. If a condition was also being updated (e.g. re-pointed to a new step), the update request would fail because the platform had already deleted the condition when the step was removed.

Changes

• Strip conditions from deleted_resources when their parent FlowStep is being deleted (platform handles the cascade)
• Promote affected conditions from updated_resources to new_resources when their original child_step is being deleted in the same push

Test strategy

• Added/updated unit tests
• Manual CLI testing (poly <command>)
• Tested against a live Agent Studio project
• N/A (docs, config, or trivial change)

Checklist

• ruff check . and ruff format --check . pass
• pytest passes
• No breaking changes to the poly CLI interface (or migration path documented)
• Commit messages follow conventional commits

Pull request overview

Fixes push-time cleanup logic for Flow conditions when FlowSteps are deleted, preventing double-delete and invalid update operations caused by server-side cascade deletes.

Changes:

• Adjust _clean_resources_before_push to remove Conditions from deleted_resources when their parent FlowStep is deleted.
• Promote certain Condition updates to creates when their original child_step is deleted in the same push.
• Add unit tests covering both scenarios; update delete prioritization to delete Conditions before Steps.
