PDP: implement EXTRA_DATA_MAX_SIZE limit #713
Description
Context
The EXTRA_DATA_MAX_SIZE limit has been removed from PDPVerifier (FilOzone/pdp#224) as it should be enforced at the service level instead. This allows different services to set appropriate limits based on their specific requirements.
Task
Implement an EXTRA_DATA_MAX_SIZE limit in Curio to prevent excessively large metadata payloads. This should validate extraData size before calling PDPVerifier functions.
Recommended limits: FilOzone/pdp#224 (comment)
