Subject: [PATCH] fix: replace @JsonProperty with @JsonIgnore on request getter
 methods
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Request objects across multiple endpoints used @JsonProperty annotations
on getter methods, which caused Jackson to inadvertently serialize request
fields into the JSON body when these objects were used in contexts that
triggered serialization. Replacing with @JsonIgnore ensures these request
POJOs are not accidentally serialized as JSON bodies — parameters are
instead passed as query/path parameters via the HTTP layer.

Additionally, refactors RetryInterceptor to instantiate a fresh
ExponentialBackoff per retry cycle rather than reusing a shared instance,
preventing potential state leakage across concurrent or sequential requests.

Key changes:
- Replace @JsonProperty with @JsonIgnore on all getter methods in GetAggregationCountRequest, GetAuthorsRequest, and GetBreakingNewsRequest
- Refactor RetryInterceptor to create a new ExponentialBackoff instance per retryChain() invocation instead of holding a shared instance
