Api Workflows Summary Filtered

Pydantic model for FilterParamDict. A dictionary that maps metric names to their filter parameters.

Each key is a metric name (str), and each value can be:

• A single MetricFilterParamPydantic (one condition)
• A List[MetricFilterParamPydantic] (multiple conditions for same metric)
• A FilterBundlePydantic (nested filter bundle with connector)

Note: Uses extra="allow" for dynamic metric name fields. The pydantic_extra annotation tells Pydantic what types to expect for extra fields, and generates typed additionalProperties in JSON Schema.
