probod-bootstrap only needs the config struct definitions for
YAML marshaling but transitively pulled in ~40 heavy runtime
dependencies via pkg/probod. Move all config types and their
methods to a new pkg/probodconfig package and re-export them
from pkg/probod via type aliases for backward compatibility.

Replace gopkg.in/yaml.v3 with sigs.k8s.io/yaml in write_test.go to match
the marshaling library used by WriteConfig. The sigs.k8s.io/yaml library
uses JSON struct tags, enabling proper round-trip serialization of configs
with custom unmarshaling logic like ConnectorConfig.
