fix(schemas): advertise epoch seconds in expire_after request schema

The expire_after before-validator accepts Unix epoch seconds alongside
ISO 8601 strings, but the generated schema only advertised string
date-time, so every SDK had to hand-widen the type. Set
json_schema_input_type on the three request validators and regenerate
openapi.json. Runtime parsing and validation are unchanged.
