feat: update environment configuration and remove deprecated model serving

- Modified `.env.example` to set local defaults for PostgreSQL, MLflow, and MinIO configurations. - Added MongoDB configuration parameters to the environment setup. - Updated `README.md` to reflect changes in workflow input parameters and task queue naming conventions. - Removed the `ModelServing` class to streamline the codebase, as it was deemed unnecessary. - Adjusted `connectors_config.py` to align with new environment variable names and improve clarity. - Updated tests to reflect changes in configuration handling and removed tests related to the deleted `ModelServing` class.

+#### Train model workflow input (sample)

+
+A **minimal valid example** (only keys required by `TrainModelParams.from_dict`, plus a minimal `model_metadata` for `validate_business_rules`) is in **`input-sample.json`**. See also **`input-sample.md`** for SQL/MinIO notes. Optional inputs include `date_column`, `date_format`, `random_state` (defaults to `42`), `val_file_name`, and `model_id`.

-The workflow validates comprehensive business rules beyond type checking:
+`TrainModelParams.validate_business_rules()` runs after type coercion. Notable checks:

-1. **train_size**: Must be between 10-100%
-2. **variable_columns**: Cannot be empty
-3. **lag_train, lag_val**: Per-variable dictionaries with non-negative values
-4. **window**: Must be non-negative integer
-5. **low_lim/upp_lim**: Must have same keys and low < upp for each variable
-6. **target_variable**: Cannot be empty
-7. **bucket_name, file_name, experiment_name**: Cannot be empty or whitespace
-8. **degree**: Must be at least 1; must be >= 2 for Polynomial Regression
-9. **nan_treatment**: Must be one of 'drop', 'linear interpolation', 'fill linear'
-10. **scaler_name**: Must be 'Standard Scaler' or 'None'
-11. **model_name**: Must be 'Linear Regression' or 'Polynomial Regression'
-12. **Polynomial Regression requires Scaler**: Models with degree > 1 must have a scaler to prevent numerical overflow
-13. **Linear Regression requires degree 1**: Linear models must have degree = 1
-14. **static_threshold**: When `rem_static_win` is true and `static_threshold` has a value, it must be between 1 and 1000 (inclusive). If null, defaults to 1.
+1. **train_size**: Between 10 and 100 (percent).
+2. **variable_columns**: Non-empty list.
+3. **model_metadata**: Required (non-empty) for validation to succeed; may include JSON Schema definitions under `model_metadata.schemas.components.schemas` for `data_model`, `model`, and `opt_params` when you want schema validation of the corresponding kwargs.
+4. **target_variable**, **bucket_name**, **file_name**, **model_name**: Non-empty strings (no whitespace-only values).
+5. **date_format**: When set, must be an allowed frontend date format (see `validate_frontend_date_format`).
+
+Model-specific rules (for example polynomial degree and scaler requirements) live in the training stack and integration scenarios; see `docs/test-scenarios/` and `scripts/run_training_test.py` for scenario-based examples.

- **Static Window Removal requires DatetimeIndex**: Scenarios with `remStaticWin: true` require data with a timestamp column for the `TimeSeriesDiscontinuityAnalyzer`

-Steps performed (default):
-1. Upload the CSV test dataset to MinIO using the configured `mc` alias.
-2. Insert a new experiment_run record in Postgres and capture the generated ID.
-3. Trigger the Temporal `train_model` workflow with the correct payload.
-
-Alternatives for local diagnosis (--local / --validate-only):
- example: python scripts/run_training_test.py --scenario 01-linear-regression-basic --local --csv docs/test-model-data.csv
- --validate-only: Validates scenario parameters only (no MinIO, Postgres, Temporal).
- --local: Runs the same training pipeline locally (validate + load CSV + train +
-  after_train_calculation). Use to get full Python tracebacks for debugging.
-  Does not upload to MinIO, insert DB, or start Temporal.
-  By default skips MLflow save; use --local-save-mlflow to also test saving to MLflow.
-
-Prerequisites (default flow):
- `mc` CLI configured with alias defined in MINIO_ALIAS.
- PostgreSQL accessible with credentials in environment variables or defaults.
- Temporal server reachable without TLS on TEMPORAL_HOST / TEMPORAL_NAMESPACE.
- Python dependencies installed (see requirements.txt / requirements-dev.txt).
