Get Entity Data

Passthrough GET /entity/data — supports action in {get, export, picklist, get_entity_ids, aggregate, chart_config}.

All query params (entity_type, action, page_size, page_num, match_filter_dict, sort_dict, search_text, tenant_scope, use_native, group_by_fields, aggregate_field, date_field, time_grain, entity_ids, export_to, export_settings, get_count, ...) are forwarded verbatim. The frontend is expected to JSON-encode array/object params.

Returns the upstream envelope unchanged so callers can branch on result (1 = success, 2 = error).
