fix: Make timestamp_field_type default to None in FeatureViewQueryContext

Jwrede · Jwrede · commit eb61ce768d70 · 2026-05-14T06:42:11.000Z
Callers that do not use DATE-typed timestamp fields (e.g. Spark offline
store tests) should not be forced to pass timestamp_field_type. Adding
a default keeps the new field backward-compatible.
