Consolidate 4 separate ModelType enum definitions (ml 15 variants, model_loader 7, campaign 2, job_spawner 4) into a single canonical definition in common/src/model_types.rs with the union of all variants and all methods (file_extension, as_str, to_db_string, weight, from_str, Display). - ml/src/lib.rs: replace 15-variant enum with re-export - model_loader/src/lib.rs: replace 7-variant enum with re-export, update PascalCase names (Dqn->DQN, Tft->TFT, etc) - ml/hyperopt/campaign.rs: replace 2-variant enum with re-export - services/ml_training_service/job_spawner.rs: replace 4-variant enum with re-export, MAMBA2->MAMBA - Remove orphan impl ToString in ml/observability/metrics.rs (Display now provided by canonical type) - Update backtesting_service and model_loader tests for new names Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
