Eugenio 56bda498b5 Refactor(ingestion): introduce ClassifiableEntityAdapter to eliminate scattered isinstance checks (#27716) ... * refactor(sampler): introduce EntityAdapter to centralise per-entity classification logic Replace scattered isinstance(entity, Table/Container) branches across processor.py, pii/base_processor.py, patch_mixin.py, and metadata_rest.py with a single EntityAdapter strategy pattern in sampler/entity_adapters.py. Each adapter encodes get_columns, set_columns, patch_fields, build_sampler_kwargs, pipeline_config_class, and service_type for one entity type. _BY_ENTITY and _BY_PIPELINE registries make lookup O(1). Adding a new classifiable entity now requires changes to entity_adapters.py only — no other ingestion files need to change. Also extracts build_database_service_conn_config into sampler/config_utils.py and updates the developer guide accordingly.
