refactor(functions push): tighten manifest path

- Drop redundant is_object() pre-check (validator handles it).
- Pass entry project_id/name as raw Option<&str>; resolve_project_id
  already trims and filters empty.
- Use take() on args.manifest instead of clone().
- expect("validated above") instead of if-let-Some on as_object_mut.
- entry().or_insert_with for if_exists default.
- Trim doc comments and verbose assertion messages; the spec is the body.
