MODAUD-271 Fix cancellation reason deserialization with consortium source field

[zakletskyi-epam]

MODAUD-271

Purpose

Fix deserialization error when processing cancellation reasons from Consortium Manager that include a "source" field.

Approach

Modified the cancellation_reason.json schema to set "additionalProperties": true instead of false.
This change causes jsonschema2pojo to generate the CancellationReason Java class with @JsonAnyGetter and @JsonAnySetter annotations, which instructs Jackson to accept and store any unknown fields in an internal map instead of throwing an error.
